idoling problem

[carguy]

When I start it up cold, it idols up like it should. When it warms up it shuts off or stalls out, but it starts right back up again. It keeps stalling out, what could the problem be?

?

It sounds like an iac but it could be many things - what is your vacoom at idle .?

One of your vacuum hoses are cracked or not in place, you can almost count on it.

I think your IAC is out of adjustment.

Do you have a scantool?

Assuming the IAC is set too high.......you can open the throttle blade a turn or so on the screw...... and reset the TPS back to .46 or so with the throttle closed.

A scantool is invalueable in setting the TPS and IAC correctly.
