does anyone know what would make the car idle so fast???? starts ok and all of a sudden will pick up once its warm???? motor has just been rebuilt so not sure if a tune would sort it out or its a sensor somewhere... help!!

i had a 300zx and it had the same problem and it was caused by the ptu so maybe its poor contact on your ignition unit thingo lol i got a brain fade hopefuly you know what im talking about

think it might have helpedmore if u just replied i dont know ....

check the plugs on the ignitor box thats what i meant, spray some inox on em or somethen and i'd probably check the coilpack loom too

thanks guys i will check the ignition system. any other suggestions would be great.... cheers

It's likely to be your idle control solenoid, or that small cylinder shaped thing with the green plastic on the end - Or what is controlling it.

It's on the inlet manifold in the middle on the right.

It could get stuck open, I know the stepper motors on the SR's that control the idle are prone to playing up.

thanks for your suggestions guys.

did u get it working adjust the tps

what tacho are you using? and what does it idle at before it goes up? i had a similar thing,, but i have no AAC or FICD solenoid, mine idles low when cold, but goes to the right rpm when warm. like kegs said is your idle switch and throttle sensor working or adjusted properly.

why does everyone immediately head for the electrics
is the cable sticking?
do you have the water running through the throttle body to prevent icing?
is the throttle plate all gungy with crud?
start with the basics
