mga malulupet na mechanico jan need help willing to pay

[gerome0123]

my problem po yung car ko 2006 model vios bali nag jejerk sya kapag nag gagass ako parang kinakapos sya lalo na sa pataas
at ito po yung napansin ko sa kanya bali kapag nag start ako medyo kinakapos din sya sa start...kapag bagog start sya nag gagass ako hanggang 6000 rpm tpos kahit naka gas ako bigla sya babagsak hanggang zero tpos parang mamatay sya(withaircon)....


background check:
1. nag simula ang jerk nung pinalitan yung magnetic clutch nya
2.pinalitan narin ng gas pump pero walng ng yare nasayg lng pera wahahaha

willing po ako mag paayos sana po my makatulong sakin at makaride ako ng ayos hehehe salamat po
around manila area lng po sana

It's not a good idea to bring the rpm to 6000 during a cold start. Since it started after replacing your compressor magnetic clutch then have the shop check for problems. The idle control system of your car should raise the idle when you turn on the ac. It seems from your description that it's not working properly. It could be many things from vacuum leak (a vacuum hose was accidentally removed), idle control system suddenly not working, a ground is not installed after it was removed or wasn't tighten, or the compressor is experiencing high pressure. If the one who replace the magnetic clutch wasn't able to find it then bring it to a better shop.

any recommended shop? chaka ano ba yung sasabihin ko sa mechanico kung sakali? e check yung magnetic clutch??

ka symb sa totoo lng tatlong mechanico na ang tinanong ko tungkol sa magnetic clutch ko walan dw connect yun???

Up lang natin ito.

In a way, medyo magkapareho tayo ng experience up to the part na sobrang baba ng idle.

Ang sa akin naman, Kapag inistart ko, kailangan maghintay muna ako at least 5 minutes bago ko ibyahe. Kung hindi, mamamatayan ako ng makina everytime na hindi ako umapak sa gas. Mamamatay makina kahit sagad na apak ko sa clutch and/or kailangan ko magbrake / lumiko. Pero once na maka-bwelo na yung kotse, parang wala naman na problema yung kotse, until the next startup. Minsan, inistart ko ung kotse, idle lang ako for 5-10 minutes, with low aircon setting, nanginig yung makina, then namatay na lang. Para ma-start ko, start kotse, apak sa gas (maintain sa 3k RPM) for a few seconds, then pagbitaw, biglang todo-baba ng idle. Pero ganun nga, kapag nakabwelo na, normal RPM ko without AC ay 400, with AC mga 750.

Ito ung problema ko kaya tumataas ang gas consumption ko nang hindi man lang ako nakakalayo, kasi kailangan ko mag-idle sa parking area bago ako lumarga.

No, you're not going to tell them that there is something wrong with your magnetic clutch because it may or may not be the cause of the problem. Like I said from my previous post, it might or might not be a connection to the magnetic clutch. Just tell the mechanic all the issues that your car is having and then tell him that the most recent work that's been done to your car is replacing the magnetic clutch and replacing of fuel pump. Then it's his job to look for the problem. It could be on of the things I mentioned in my previous post or not at all or it could be the mass air flow sensor.

You can try Servitek or Speedyfix or Dallas.

You didn't mention what car. I think your problem is with your idle control system or idle up solenoid or iacv. 400 rpm without aircon is low. Usually it should be around 700-750rpm without aircon. Try bringing it to a reputable shop to diagnose it.

Vios 2006, second-hand. Acquired January of 2015. Problema ko na to simula pa lang. Although hindi ko naman ginawang big deal dahil wala naman ako naging problema once na malagpasan ko yung first 5-10 minutes. Yun nga lang, hindi ako nakaka-alis agad gaya nung iba. Last na pina-check ko ito ay hindi din naman naayos dahil hindi ganun maalam sa talagang electricals yung last na pinagpalinisan ko, nilinisan nya yung servo (hindi ko alam ang tawag). Pero ang sabi nya, itinaas na nya daw ng idle, pero sa totoo lang ay hindi ko din naman ramdam yung nabago (kung meron man)

Sometimes they refer to the idle up solenoid as servo. If that was clean then it should have resolved the problem unless the servo is dying already. It seems that there is something wrong with your cold start system. Typically, vehicle will idle at around 1000-1500rpm upon start up then it will slowly go down once the temperature of the engine goes up. In your case, your car starts at low rpm.

Try resetting the ecu by:
1. Remove the negative terminal of the ecu with the engine COLD. Reconnect the negative terminal after an hour. Turn the ignition to ON (DO NOT START THE ENGINE), press the gas pedal fully then release. Do this for a couple of times. Then turn the ignition off. After that, start the car and see if there's any improvement.

If no. 1 doesn't work, try this:
2. With the engine cold and all accessories/lights/aircon are OFF, start the engine and let it idle for a few seconds then step on the gas and keep the speed at 3000rpm UNTIL THE RADIATOR FAN COMES ON TWICE. After the rad fan comes on twice, release the gas pedal and drive around for a while with the aircon OFF.

If resetting the ecu doesn't work, try to clean the throttle body if you know how to. Otherwise, look for another mechanic and have it check again. It would also be helpful if you can borrow another working idle control valve or servo to check.

mahal po ba dun sa tatlong shop na nirecommend nyo? ask lng po?

actually yung sakin, kapag nagstart naman sya (cold start) 1.2k RPM, so no problem. Once na medyo ok na sya, bababa na around 700, then minsan nga ganun 400-500, medyo nanginginig. Pero minsan, kahit 400, walang nginig, pero ito yung kapag medyo nakapahinga na after mo mai-drive nang malayo layo.

Minsan, nagdrive ako sa NLEX, naka aircon, nmalapit na ako sa exit tollgate so medyo nagneutral na ako dahil may pila pa palabas, from around 1.3k idle, bigla bagsak, to around 600, hindi naman sya namatay, kinabahan lang ako at baka bigla mamatay pero wala naman.

Sa totoo lang mahirap ipaliwanag sa mekaniko yung problem, unless sila mismo ang magpunta sa bahay at magstart ng kotse, para idrive around. Kasi kapag ako mismo ang nagdala sa talyer, hindi na mare-replicate yung problem, dahil nga uminit na makina. Dun sa kinwento ko na mekaniko, sya ang kumuha ng kotse sa garahe, sya pinagdrive ko, nagaircon kami (low), nagmenor lang sa humps, bigla namatay. Pero hindi sya nag-jerk, tumigas lang ang manibela (dahil walang power steering) pero nagko-coast kami. Start uli, nagslow-down lang nang konti (dahil may kasalubong), namatay uli.

Servitek and Dallas shouldn't be expensive. Servitek has many branches while Dallas is in Tomas Morato. Speedyfix is in San Juan and a little pricey but they do good work.

Judging from your description, I'm guessing that there's something wrong with your idle air control solenoid. Another very less likely possibility is the ecu. You are experiencing drop idle problem. I have experienced that in my car before especially with the air conditioning on and I would remove the idle air control solenoid and clean it with carb cleaner and compress air. After that everything will be good. On very rare occasions, I would need to clean the throttle body as well. There are instances when cleaning will not solve anything anymore and that's when you need to replace the unit. Another check that you can try is, when your car is warmed up and idling at a normal 700 rpm, remove the electrical connector of the iacv and see if the idle will drop (it should) then plug it back in, the idling should increase. If not, then there's a big chance it's your iacv. You can do the same thing too with the idling at 400rpm.

Try other shop, because, a good shop or mechanic should somehow have an idea then he'd start from there especially if he's been working on cars everyday.

Actually hindi lang naman sa Honda. The IACV/servo is a mehanical part getting a signal from the ECU. In time, the part wil get dirty since air passes through it. So when the idling is behaving badly, that's the first thing you clean. Then next is the throttle body. Other vehicles also has an IACV/servo and it gets dirty as well. Sometimes troubleshooting these idling gremlins need a systematic approach.

papalinis ko nga ung servo, pasok ko na din sa casa para macheck ng ayos.. salamat sa reply sir motoro.
