idle trouble and cutting out.

[joehandley94]

Hi, new member here.
I have a 1999 T reg. 1.2 16v corsa b.

It starts fine but when idleing its at very low revs (below 1000rpm)
and when the engine is cold it cuts out when clutch is down and car is slowing down. (sometimes when warm too)

when the engine is warm the car sometimes revs itself when idleing but not all the time.

I have changed the Idle Control Valve for a brand new one and problem still happens.

All engine management sensors were changed 6 months ago (cam, crank, MAF, accelerator, temperature, lambda).


any help please?

Were the sensors generic or genuine ? Corsas tend to just break genric parts quite quickly

[joehandley94]

they were al genuine parts i think, the idol control valve ive just changed is generic, but it was still doing it straight after i changed it so doubt it would have broke it that fast

[johnny]

Have you had the codes cleared since replacing the parts

[joehandley94]

no i havent, could that be causing it?

[johnny]

Yeah if the ecu is storing old codes it could be throwing itself off

[joehandley94]

okay i'll get that done and let you know if it works, thanks for the help

[joehandley94]

that didnt work so i changed the idle control valve and throttle sensor for new bosch ones and that did the trick
