Over the past 2 days I have done the following:

replaced the plugs with autolight 3923's gapped to .040
took off the throttle body and cleaned it some (it didnt look that dirty)
just replaced the pcv valve but again the old one looked fine.

after doing all of this if anything the idle is the same or worse than before.

any other ideas?

 

Have you tried hooking up a vacuum gauge to ensure there are no leaks in the system?

Could be a fuel injector or even the fuel filter.

 

My next step I was thinking about looking at the injectors. Thanks.

 

try resseting the computer, by draining your batter a few have said it works, search computer reset

 

Ive reset it twice, once for the throttle body cleaning and the other for the plugs. I didnt reset it for the PCV though as I was told I shouldnt need to. If I should let me know and I'll reset it again.

I just picked up some Seafoam and will be doing a gas only treatment and see if that does anything.

 

hello

i was looking around the forum and i noticed this thread and i have the problem. The other day i went for a drive and i was stopped at a light and my truck my idling rough and then it decided to shut off.

so if you find any solutions i would be very thankfull.

good luck

 

was your ac running?

 

try swapping out ur iac motor on the throttle body it solved my rough idle a while back, there around 30 or 40 bucks cant quite remember.

 

mine did that it was the battery it had anough juice to start it but shorted out while runnin makin it idle rough and die

 

I had that happen a few times when I first got the truck. I complained about it at the dealer when I was having a shock replaced under warranty and when they gave it back they told me they had flashed the PCM with an update. Haven't had it happen since then.
