problem about mivec

[steven_chong8]

helo~~ anybody can help me ans tis problem,my engine timing, when i wan to stop at traffic light, sure i will free gear and brake slowly, after i free gear, the timing will maintain at 1200 -1400(r.p.m), after i definately stop the car,the timing only will drop down to normal(800-1000),anybody can help me solve tis problem? tell me tis is normal or something wrong??? hopefully u all understand wat i am trying to say....thanks....

RPM means idle lar..not rpm = rpm
no offence

huh??... rpm means idle??>..
revolution per minute wor... equals to idle ga??... never knew that...

 

[gavan]

ahaha, idle is idle(not moving) lerr...RPM is revolutions per minute lerr.... :D ahaha, erm, your problem also i face it sometimes, dunno wether its accelarator cable stuck or just the vacuum thing, not sure leh..i just leave it only, cause mine sometimes will stuck @ 2000RPM, and never wanna come down unless of course i press the pedal to the metal a few times, mine sounds more like a accelarator cable problem than a idling problem tho. so im not too sure either :( hmm....

did u open ur air con when this problem happen ??

 

[tajulsans]

Sounds like ur ISC about to kong.. happen to my car..

 

[simefly]

i presume that its the cable that connects to the butterfly at your TB. The Air Intake of a MIVEC has a higher air compression rather than ...lets say 4G93. So the butterfly tend to stay there for a while before it falls back to idle position. Maybe a lil WD40 would help do the job... DIY only if you know how to do it... otherwise go to your respective mechanics.

As for the ISC, you might want to have a look at that, but i would not conclude just then yet...

Cheers... :)

ya me driving gsr oso got this problem

 

[fstr]

when u totally stop da car for sure ur idling will go down more as it consumes more power when motionless, as your cars generator is not charging...applies to all engines.

 

[gsrTurbo9166]

that's mean it is normal la
rite???

 

[steven_chong8]

boyzone,yaya....this problem only will happen when i on the air con....u know y?

 

[boyzone]

that's ur isc calebration problem, just check ur isc with multimeter, should give u in between 45ohm to 65 ohm. if no problem ,I think u should took out ur throttle body to clean and service it, after that to tune back ur idling, this should help :D

so u didnt solve the problem lah? but if don solve it, feel not nice o....right?

for my experience... the rpm will stay high around 100+ or 200+ from your idle let say 1000 to 1200 rpm on roll...

if high than that probably ur isc is spoilt... because face such problem before and now no more... if spoilt will stay at above 1300... should be like this because very wired

problem of mivec

for my experience... the rpm will stay high around 100+ or 200+ from your idle let say 1000 to 1200 rpm on roll...

if high than that probably ur isc is spoilt... because face such problem before and now no more... if spoilt will stay at above 1300... should be like this because very wired

wat is isc? and if really spoilt, how much it cost? and is it difficult to change?
