Check if your idle control solenoid and it system is working properly. Then check if your condenser fan is spinning fast enough because if it isn't the a/c compressor will go into high pressure and put additional load to your engine thus might be the cause of your idle drop. Check your temperature gauge as well whenever it would stall.

Noted yan sir, double ko ulit yan. possible sa set up lang ng idle un. Thanks po

Mga Bossss... pa help nman po....

Hyundai Grace 1995 and sasakyan ko D4BA ang engine.. ang problema po kasi, mahina humatak ung van ko. ok naman sya pag patag ang dadaanan kayang kaya nya. pero pag akyatan don sya nahihirapan pag maraming sakay pero kong ako lang sakay kayang kaya.. dati po kasi kahit naka 3rd gear ako umaakyat sya ng walang hirap kahit maraming sakay. at napansin ko pag naka 3rd gear ako pag inapakan ko na ng kalahiti ung accelerator may umalabas na usuk na maitim. at hirap ung sasakyan. ganoon din pag 2nd gear pag tinutudo ko ung apak ksi akyatan ang itim ng usuk at hirap ang sasakyan ko. kaya pag paakyat na at nabitin na balik ako agad sa 1st gear para makaakyat. dati rin po pag nakahinto ako kahit naka 2nd gear ako kayang kaya nya tumakbo ngayon kaylangan nsa 1st gear muna para tumakbo sya. gusto ko po sana sya ibalik sa dati nyang power lalo na sa akyatan... mga bossss ano ang mga dapat palitan at ipaayos nob talaga ako pag dating sa engine...

note: nahihirapan lang ang van pag akyatan na maraming sakay. 2nd gear and 3rd gear...

maraming salamat bosss.. sa sasagut....

Check your clutch maybe it is starting to slip already. Next, is your van diesel? perhaps it needs a tune up as well as injector pump calibration. Check your air filter if it's still clean. Black smoke usually means engine running rich - more fuel than air.

ok pa naman ung cluch kc wala naman akong nararamdaman na dumudulas ung clutch. opo boss diesel ung van ko... try ko po palitan ung air filter if magbago ung hatak at mawala ung usuk... san po ba magandang magpatingin ng mga kanitong issue na malapit sa amin? Quezon City ako. ayaw ko na ksi patingin sa dati kong pinapagawaan kc ang mamahal nila manigil at kahit ok panaman pinapapalitan na nila kaya napapalaki ung gastos....

Replace the air filter if it's very dirty otherwise there might be other problems like the injection pump. You can try Speedyfix in San Juan, they're not inexpensive but they do a good job. You can also try Dallas in Tomas Morato QC.

Hi po, ask ko lang, meron akong nissan sentra eccs 1992 model, matic, ok naman sa
First start, RPM, etc, pero kapag nag init na makina... mga 10mins drive, namamatay sya, then iistart naman kapag inistart ulit,
Tpos mamatay ulit then start ulit, tpos bigla mamalya
Engine, bumabagsak rpm, pag napahinga ng unti engine, back to normal na ulit, then mag iinit, patay na naman...
Nagpalit na po ako ng injectors, fuel pump at nilinis na rin throttle...
Ano po kaya sira ng oto ko....? Salamat po sa sasagot

Stalling issues can have a lot of reason and a systematic troubleshooting process should be done otherwise you'd end up swapping parts which are not really faulty. I'm not sure if your car has a main relay, on a Honda, when it start stalling after the engine is warm it is usually the main relay. Usually, reflowing all the solder joints will fix it. Another cause would be your ignition system, sometimes a bad igniter (if you car has one) inside the distributor will cause a car to stall but it will start right up after letting the engine rest. A failing distributor can also contribute to it. A failing MAF sensor or EGR can also play a role.

Last but not the least, the ECU. Perhaps there's a problem with the ECU. I experienced stalling issues when warm with my Honda before. I would have to let is rest for 20 minutes before it starts then will die again after a few minutes of driving. On my car, the fuel pump wasn't priming so I replaced it with another fuel pump I had laying around but still the same problem. I check the main relay because it controls the pump but the relay is good. Then when I'm almost certain that it's the ecu, I open it up and found a leaking capacitor which luckily didn't burn through the PCB of the ECU. I had to order OEM capacitors from abroad and even replaced the IC that is responsible for fuel pump priming and those cost me more than 2k. However, it didn't solve the problem and I was heartbroken so I had to start from scratch again and started looking at each tracks and component inside the ecu and I found a weird looking 1k ohm resistor which seem to be infested with termites. I replaced the 1k ohm resistor which cost less than 10 pesos and problem solved. If you can borrow a known good ecu then that would be best or at least have a look inside. By the way, does your check engine light comes on?

Hi, nope... check engine light does not comes on.... temperature gauge is also normal...

Then you will need more patience in finding the gremlins responsible for the stalling.

Mga sir need your advice

Mitsubushi Space Gear 2004 Model, Automatic Gas

Issue Pag naka ON ung aircon, Engine stop pero mabilis naman magstart, when shift to Drive and put Gas, namamtay ulet.

Pag naka naka pahinga na ng ilan minutes working na ulet , malakas na ulet humatak. wag ka lang gagamit ng aircon.

Last week kala ko nasolve ko na ung issue nya. kasi before pag nag ON na aircon may maingay na parang may sumasabit dun sa belt,

Upon check up nakita may tama na ung driving pulley. need na palitan.

Nung napapalitan ko, Ok naman na ung running na ulet wala maingay pag nagoopen ako ng aircon. di namamtay ung engine.

Week after nun natraffic ako engine stop na naman, it takes minutes bago umandar ng ayos (naka off ung aircon.)

Update

We found out ung possible na problem ng Space gear.

Nagpa cleaning ako ng throttle body and Cervo.

After ng cleaning road test kung babagsak pa rin un rpm pag naka open ung aircon.

Result nya lahat ng gear except sa DRIVE dun cya nagkakaproblem , pag on mo ng aircon babagsak na ung rpm pag nasa Drive shift.

As per suggestion nun mekaniko possible grounded ung wiring ng aircon and walang led light indication ung letter D sa dashbaord.

Recommendation nila rewiring daw ung aircon.

Shifting to drive puts a load on the engine so when you turn the A/C on, you're introducing additional load. I hope they set the idle speed correctly after cleaning the TB and Servo. I didn't know that a grounded A/C could still work or run and luckily it just affected your idle and didn't catch fire. If there's no additional problem with your engine then the "D" not lighting in your dashboard is just a case of busted bulb. I guess time to do the rewiring to see if it's the problem. Good luck.

sir yung ac ng vios 1.3 e 2011 model ko nawawalawala.. ano kaya ang problema?

Good Day Sir, ask lng po ako about sa oil leak ng oto ko.napansin ko kasi pag gumagamit ako ng aircon tska sya nag kakaroon ng oil leak.wla pa po kasi alam masyado sa oto. pa help nmn po before ako mag punta sa auto mechanic. salamat.

Maybe the compressor is on its way out already because if there's a problem with your auxiliary fan then it will not just come and go. Better bring it to an a/c shop to have it check. Who knows maybe it just need some cleaning. Car a/c is similar to home a/c where it will need to be clean.

Is it really oil? Because when a vehicle's a/c is on, it is normal for water to be present on the floor just beneath the passenger side firewall because there's a dump tube from the evaporator. To be sure where it is coming from, you better jack your car up and put it on jack stands(for safety) and look where it's actually coming from.

boss, pa advice, meron ako nissan march k11 cg10de engine, manual transmission, last december nasira ang fuel pump, pinalitan ko ng universal at naging okay, mga ilang days ang nakaraan ay biglang nag stop ang engine habang tumatakbo ako, hindi naman siya overheating, mga ilang minutes pina andar ko at nag start naman, at naka takbo ulit, yun nga lang mapapansin ko sa tunog ng tambutso nag broooot broot broot, parang hindi nasusunog ang fuel masyado, naghinala ako na baka madumi yung fuel filter, pinalitan ko ng fuel filter at nilinisan ang fuel tank...na okay ulit maganda na ang tunog at hindi na ako nakaranas ng mag stop ang engine... mga ilang days ginamit ko tumakbo ng mga 10 kms, ayun ng stop ang engine nasa daan ako kaya pina start ko ulit, mag start man siya...yun nga lang bumalik na naman yung tambutso mag brooot broot broot,naghinala ako baka spark plug, ayun pinalitan ko naman, at tumakbo lang papuntang washing mga 2km pagbalik ko naka pansin ako ng pag light ng battery indicator, pero natuloy mag stop kasi tinapakan ko ang gasolinador ...
boss yung fuel pump na nabili ko sa online malakas ang tunog na hamming.... as in marinig mo talaga, yung dati kasi walang tunog talaga..
posible kaya hindi maayos ang pagkalagay ng fuel pump?
sira na kaya ang fuel injector ko? EFI po ang engine.
may problema kaya sa ECU?( may ECU ba ang nissan k11 efi cg10de engine.?
ano kaya sa tinin ninyo boss?
dami ko ng napalitan pati battery pinalitan ko na ng bago.

Do you know the specs of the fuel pump you bought? Fuel pumps come with different flow rate. Was the pump making a loud humming sound when you first installed it? If so, the perhaps you bought a high flow rate pump. Usually high flow fuel pumps are loud. When I was still using my stock pump, I need to open the gas filler door and stick my ear close to the gas cap to hear it priming but now I'm using a 255lph (liters per hour) fuel pump, I can hear it priming while seated on the driver seat. Although the ecu is good at compensating for different factors there's a possibility that it is having a hard time matching the required fuel to the injector. That is, if what you have is indeed a high flow pump. Since, based on your post, your problem started after replacing the fuel pump then try going back to stock fuel pump and go from there.

i dont know the specs of the stock fuel pump and the one that i bought-all i know is i bought the same kind(shape) of the pump with my stock pump but the new pump says it is for nissan sentra 1985 to 1990 model-my car is nissan march k11...the pump didnt hum when it was first installed, it was later a day after hummming sound observed, you can hear that humming sound outside even 1 meter away.. stock fuel pump is already bad, i cant try it anymore... so for now i decided to buy surplus fuel pump that is from nissan march k11 spare. if it is really the fuel pump problem.
when i observe the engine, sometimes the sound of the muffler(engine was started) sometimes the sound is good and for a while it is not... i can smell fuel.. and blowing black smoke at first starting the engine, so i think engine was not burning all the fuel....

Smell of fuel and black smoke means that your engine is running very rich. Running rich may mean the engine isn't providing enough spark which I doubt since you have new plugs or your ecu is having a hard time controlling the fuel. Have you check your fuel pressure regulator? Try to look for another fuel pump specifically for your car, you don't need to buy original Nissan but ask around if they have replacement but brand new.
