So far i have stripped and cleaned the stepper motor and throttle bodie and check all of the pipes for any splits or leaks the stepper motor has been replaced on the 9/8/2012

Have you put a reader on it? Are any faults logged? Looks like the map sensor could be playing up. How does it drive?

yes i have put a code reader on it no codes logged and when the stepper pipe is connected the drives like a bang of p** accelatoring away and then backing off

Have you checked the stepper pipe for blockages has a coil pack failed or spark plug when was the fuel filter last changed could there be a loose plug anywhere? These are the only thing that I could think of

Reset the icv?

i have just been to the scrappies and got another map sensor and stepper motor even tho my one stepper is new as of 9/8/2012 and also a standard airbox to get rid of the induction kit

how do you reset the icv

can anyone shed any light on my problem

Turn the key to pos 2, then push down and release the accelerator pedal down 5 times, then turn the key back to pos 0 then try and start the car :)

Sticky throttle body get a aluminium one.
