I have 2 questions:

First, my O2 sensor is mulfunction. I think my car are running rich becaz I have a bad gas milage. I just wondering what will happened or affected if car running too rich??? Will running rich caz engine stall???

Second, it seems that I do not only have the TSB engine stall problem, but idle hunting from 900~ 700, sometimes even stall when AC is not, clutch is not in and gear is not in...so i just want to check if this is clutch switch related?? How can I know if the clutch switch is failed physically and internally????

Thx

Do u guys think it is clutch switch related problem?? How can I know if the clutch switch is not worktng??

Simple,

don't depress the clutch pedal when starting the car. If the car starts without you depressing the pedal then the clutch switch is shorted. If it does not start and you have to depress the clutch to start it, then there is nothing wrong with your clutch. I would check for vacuum leakage, it's usually the main cause of idling problems.

 

o
u serious??
i really have vaccum leak somewhere in the turbo or intercooler piping~
i can hear air sucking in when turbo kicks in

 

You sure it's not blowing *out*? That's what happens when there's a leak and the turbos are boosting.
