My MY00 recently killed its Idle control valve,
whilst i was trying to find out what was wrong with it i adjusted the TPS, and replaced the lambda for a universal cheapie off fleabay,

when i finally got my new ICV, it sorted the car reving itself, but now when the car is cold as soon as i touch the throttle the car want's to die, the rev's stutter until it picks up ( above 2k ) then it's fine. Well until you let it idle again.

ive re- adjusted my TPS to how it was before ( 0.51v )

Do you think it could be the Lambda sensor??

im thinking whilst the car is on open loop its reading the duff lambda ( which is reading 0.00v until you lift off the throttle, on which then you get a reading i.e ( 0.82v ) is this normal??

then when it gets warm and goes into closed loop it stops relying on the lambda readings?

anyone have any knowledge of this?

thanks

anyone mad similar experience?

 

the lambda sensor is used for cruise and idles and lights throttle cold and warm...

the voltages you mention appear to be in reverse.. try unplugging it and see how it drives..
