Anyone have any idea, what else could be causing my stalling problem on my 98 5.2? I have had low idle for about 1 year now. 3 months ago I replaced the I have tried the following:
Replacement of Idle Control Motor Valve
Cleaning the Throtle Body
Replaced Air Filter
Replaced EGR
Plugs
Battery seems ok

WHAT"S WRONG WITH IT??????

Plugged cat! Bad O2 sensor! Maybe plenum gasket. Haven't got time to look right now, but there are threads here on how to test for these conditions. I will look them up if I get a minute. Other than that it looks like you have done the logical things so far.

Vacuum leak.

No vacuum leak, I checked. But it does occur after warmup primarily, but not soley

I had that happen on my old Dak. It was the O2 sensor. That is what I would check.
