Yeah, the gas has been crappy around here lately. Been putting it at the shell for the past week, maybe thats why its not doing it now. Oh, and the cats have been gone for a long time.

 

I had a similar problem happen to me. I know this sounds too simple, but try disconnecting your batter for about 30 min. and then reconnect and start the truck up and just let it idle for about 20 without A/C.

 

Elton amazingly we had the same ISSUE . Went to Flaco and the issue went away. Had to get another Computer but its well worth the $40 I paid for it. Tuned it 1 time and it ran it's best 13.89 in the 1/4 mile....Call me

 

I really dont think it is in the tune. It has been tuned for a long time now and this is a new issue that has just popped up.

 

What rpm does it idle at? Mine did the same thing and idled around 500 rpm, tuner said he thought it was pcm issue and i got a retune. Now my idle is set at 700 rpm and it hasn't done it again.

 

He has had that tune for a good long time now,sorry to disappoint you!

 

The issue has gone away. In fact, the truck is running harder than ever. I cleaned everything and ran some fuel treatment through it, and only put gas at one certain station.

 

well good for you Elton. BUDDY
