Well my 2 codes were 42 & 11. 11 was self inflicted as I removed the cable to the crankcase sensor, allowing car to crank over on the starter for circulating oil to the new turbo fitted prior to starting the car. I don't know if 42 would be connected with this.

Basically car appears to be over-boosting since new turbo was fitted.

I've found code 42 is active - Idle controller, so I'm wondering if this is caused by the overboosting. Can anyone confirm if this is related in some way. If not I'm doing the ECU reset tomorrow and see if fault occur's again.

 

Anybody help me on this one !!!!

 

caz,

not sure that this would be the cause. it's the stepper motor (usually white plastic round-ish block to the right of the throttle body inlet- with 4(??) wires coming out of it) that controls a small amount of bypass for air into the inlet to smooth idle out & put the revs up when say A/C come on etc.

the only way I could see it causing spikes is if it was stuck open, even ON boost, and then shutting quickly. but if it was stuck open, I imagine you car would run like a bag of brown smelly stuff ! & I take it, it's not?!?

I'd do a CLEAR ERROR CODES reset (green & black connectors I belive) rather than an ECU reset & see if it comes back.

cheers

Thx Steve, will clear codes tonight.
