Modena Posted June 21, 2006 Share Posted June 21, 2006 My car for some reasons has stalling problems after hitting boost when its warmed up. It has stalled, then when I turned it back on stalls again, then on second time it starts but at times when I gave it some gas it splutters and then plays. THis only happens when I rev it past 2000 RPM, I drove below 2000 rpm yesterday and didnt play up at all. What could this problem be??

mad082 Posted June 21, 2006 Share Posted June 21, 2006 how old are your plugs? what type and gap are they? does it only stall when you are decelerating? if so, there is a good chance its your plugs. mine would stall after giving it a bit of stick then slowed down. put new plugs in and went away. very much doubt it is the bov. seen plenty of skylines with atmo bovs that run fine. most common problem with atmo bovs is people put them on then don't tension up the spring so they leak. and when they do run rich on gear changes it is only for a split second. they don't constantly run rich.

AFM is clean. no idea... i think it may something to do with the fuel system (fuel lines, fuel pump)... thought maybe u guys could chime in with something else...

anthonymcgrath Posted June 21, 2006 Share Posted June 21, 2006 getting same prob myself at times - seems ok and revs are stable (but higher than normal - idling at 1100rpm ish) but after accelerating and using boost - come to slow down and it can stall here n there. only thing I can think of personally for mine is AFM on way out as other owners I know had similar trouble Link to comment https://www.sau.com.au/forums/topic/123104-problems-after-boosting/#findComment-2273553 Share on other sites More sharing options...

mad082 Posted June 21, 2006 Share Posted June 21, 2006 could also be idle control valve. we did some 'tuning' on my car and the next day idle was all over the shop. first it would idle high, then it would stall, then it would hunt. ended up taking the idle control valve off and giving it a good clean. sorted it out for me.

RANDY Posted June 21, 2006 Share Posted June 21, 2006 I put money on faulty AFM. A mates car did the same thing. Started then stalled after one or two seconds. I unplugged his AFM, then started it with a bit of throttle in there, and he limped it home. It would cut out over 2000rpm (exactly), but it made it. New AFM and it runs perfectly.

mad082 Posted June 21, 2006 Share Posted June 21, 2006 idle control valve is at the back of the motor on the drivers side. it sits at the end of the plenum at the top. it has 2 pipes coming out of it, 1 of them underneath it. it has 2 plugs on it. if you look at it from the drivers side you will see the idle srew (about 8mm in diameter and takes a flat blade screw driver... i think) it is 3 screws to get off, the 2 plugs and 2 hoses. the bottom hose is a bit of a pain to get on and off. to clean it you need carby cleaner, and optional is some pipe cleaner. just give it a good spraying. i took the little motor bit off so i could clean it completely. then when you put it back on you may have to adjust your idle, unless you get your screw back in the same spot.

Modena Posted June 21, 2006 Author Share Posted June 21, 2006 The mechanic (non import) rang me today said it may be my turbo timer... yeh right. he said the car stalled on them once... i think they may need to send it off to import aware mechanic.
