94 gt idle
 

I have a 1994 gt, Ive put a small cam, timing chain water pump and new rollers in the car. The car is back together and will not idle when the car warms up. Im changing the idle air control today. Any ideas let me know

did u use a chip to modify your computer for these changes? tweeker?

if not thats what i'd invest in. the 94/95 computers are touchy..

I wouldn't start buying things till you have found the problem. Chances are slim that something unrelated broke at the same time you changed cams. First i would reset the computer and if that dosn't work i would check the vacuum.

if something was broke or installed incorrectly then that would be the problem. maybe.. otherwise when modifying these cars u have to modify the computer to gain the most power and driveability!

Thats why I said something "unrelated" like sensors, the IAC, etc... And the vacuum gauge will tell him if something was not installed right like a leaking gasket, rockers to tight, etc... The stock ford mass air eec's will be able to handle a mild cam swap without any special tuning.

I called crane cams and they have told me that the 1994-1995 computers are very touchy and have a hard time relearning information. They told me that I will need a (a 9 l ecu upgrade) and since then have heard of several people who have done this. This is a new computer and wiring for the car. Keep you guys imformed.

IMHO...the easiest way would be to purchase a 94/95 Cobra PCM (box code J4J1). I know the Ford dealer around here is usually $150. I normally change this with the chip but it is plug-n-play and works good...you will have to upgrade the injectors to 24# and a new MAF. However eventually you'll want to change this anyhow.
