95 gt Idle Surge Problems

[stangman1995gt]

Car basically shuts off when I come to a stop. Idle will surge for a few seconds and then car will shut off. I have cleaned the MAF and still nothing. I see this is a common problem for the 94-95 stang. I have never did any thing with the timing, fuel pump is still oem. Stang has 60,000 miles on in. Any Ideas?

you need to clean or replace your IAC (idle air controller)

I replaced the IAC valve and now the stang has a mind of it's own. I can leave work and not have to press the gas pedal and the car will go like it has cruise control on. When I start it up, it idles at 1800 rpm for about 10 seconds and drops down to base idle. Im lost...... Any ideas?

make sure you adjust it correctly when you put on the new one

One thing you have not mentioned was how the idle was set on this car. Unhook the battery for around 15-30 mins. and set the idle as described in here.

BTW some aftermarket IAC suck....

i agree, you have to set the base idle first

Did the base idle thing as it describs and still nothing has worked.
