G'day guys,

my mates got a EA CFI, and its constantly rev'n, at lights it revs and pulls against the brakes, this reving sometimes goes down, but it takes like 40 seconds..

would it be the TPS?, i remember reading about somebody who had the same problem, but couldnt find the thread..

if it is the TPS, how hard is it to change? and what kind of money is he up for?


any advise would be greatly appreciated.


Thanks.

JJJ had this same problem and from memory he cured it by loosening it and moving it around to get 1v in one of the wires. Not sure though.

Easy as piss to replace, even easier to nick one from a wrecker. Not that I recommend that kind of stuff

What trans does it have? If 3 or 5 I can help with a TPS as I've got my old one. If it's 4 speed you'll need to find a 4 speed CFI and get one out of that, as the 4 speeds have a dual TPS.

Cheers,

Sundeep

Pull it apart and wash it in petrol, or wd40. The put new gasket on and it should be right.

I done it on my old car (was ideling bad) pretty easy, and helped a bit.

Idle speed control {isc} it sounds like. As said clean it out...Check for air leaks, throttle cable adjustement etc as well ??

Thats exactly what my CPI EA would do, you need to measure the voltage at pin47 ECU or Green/Black wire on TPS plug. 1volt closed throttle and 4.5V wide open throttle. Mine was on 0.75V and would rev up like that when ever it wanted too. Just loosen the two screws on the throttle body and move the sensor downwards until you get 1 volt on closed throttle, tighten screws and you will never have another problem. cheers JJJ

I had the exact same problem and I got the TPS changed and it fixed it.
The symptoms that you describe are exactly what I was seeing.


I just read this post headed titled

"Everyone with a 3.9lCPI engine should read this!"

Give it a read.
Man if only I had read this before I got my TPS replaced.
