Hi All,

 

I have the obligatory Z idling problems (constantly too high - 2000+ rpm) and reckon it's down to a vacuum leak. I've changed and re setup the TPS so I'm pretty sure it's not that.

 

The car has recently had a gearbox swap Auto>Man and hence I have a whole lot more vacuum servo hoses to leak. The idle was always a bit on the high side (1100) and occasionally got stuck a bit higher (1500)

 

Anyone got any advice about locating a vacuum leak? Could I use one of those boost leak dummys Vijay posted about with the TB's held open? Or am I talking cr*p (again)? ;)

 

Any advice appreciated.

di u check the tps sesor ... connection can be bad ... mine does occassionally

Hello Rob,

 

Let me know if you want one as I've got one extra (someone has said yes and then not answered any mails:rolleyes: )

I suppose you could block off the hose that goes to the clutch servo temporarily at the balance bar and see if that makes a difference. :-S. It'd just make your clutch a bit stiff for a while.

 

Perhaps.... ;)

Hmm...

 

Fair point Mr.W, I'll give that a try - should be able to tell without driving the car anyway as it's at idle I get probs.

 

BTW it's a brand new TPS so I'm pretty sure that's ruled out.

 

Can anyone confirm whether TPS should be checked with the car running/warm or just ignition on?? I know it's been discussed before but there seems to be no final verdict.

 

Voltage is way high while idling - (almost 1V :-O) the TPS is adjusted for minimum possible voltage at the mo' - about 0.2V when not running...when the car is started voltage goes right up - any suggestions why?

 

What could making the TPS voltage rise while the car is idling - apart from opening the throttles?

 

Cheers!
