Topic: 88 Twincam Idling

Howzit guys
Was just thinking of a problem i had with my chisel shape twincam that i never could solve...took it to a no. of mechs who were dumbfounded by it. The car used to switch off wen warmed up to running temp..irrespective of weather. Wen u slowing down and change down, as soon as u in neutral, the cab switches off...but starts on the turn! The idle used to hunt as well....it was a real naaring problem..cos i always had to  have it in gear. I had changed my fuel pump twice, changed the coil, changed plug leads, throttle body, even reconditioned my injectors...but nothing helped!!!
i know its too late to wory bout it now...but maybe the info could help another fellow twincam driver if he experiencing the same hassles?
Other than that...the car went like a dream!! nice and quick :-)

Re: 88 Twincam Idling

I actaully had a similar problem on my conquest when i first bought it a few years ago. Basically it wouldnt hold idle. I solved the problem by chipping the car. Im sure that we can track down the exact cause though.
Any other ideas ? Idle control valve ? :rolleyes:

Re: 88 Twincam Idling

ok...the guy that bought the car from me sorted the problem out. said he changed the TPS. and also traced the wired to the idler unit...and tested with a meter. one of the wires was sending a negetive signal...or something...so he disconnected that wire from the battery...and no more switching off!

woth a try..

Re: 88 Twincam Idling

I had this problem

Solved by setting the TPS sensor on the throttle body

Re: 88 Twincam Idling

My 88 Gli USED to do the same thing. Som:whistling:e said maybe air in cooling system, so i bled that. Nothing. Then i just removed a vacuum pipe from the intake...and idle increases a lil, but no switching off at least for now.:cool:

But for future reference how do u set the tps sensor?

Re: 88 Twincam Idling

most certainly a sensor issue, the ICV on 16v is static, you adjust it manually on the throttle body.

you have a cold start valve as well, but it wont make your car die when warm

i think the ecu is getting a signal from its water temp sensor that is wrong, the twincam has two water temp sensors, one for meter on dash, and another for ecu(located on or near gearbox), my 88 did the same, used to hunt up and down all the time.

solved by fixing wiring and sensors, could also be bad sig from air flow meter.

get a diagnostic manual, and check each sensor according to the manual, you will find the culprit quickly
