I started my truck up this mourning And everything was fine until about half way to work when it was totaly warmed up and at stop lights or stop signs when it would idle it feels realy rough. I can feel the whole truck shaking. Has anyone else had these symptoms? It is fine while you are moving it is only there at idle. Please help if you can.

Mine is doing this, it will idle up about 250 rpm for about 1 second intermittently, very exciting if your not expecting it. I used a "oiled type" green air filter when the fuel prices were in the stratosphere for a few weeks. I'm thinking my MAF is oil fouled. Maybe one of the sites resident "brains" can tell me how to clean it. Contact cleaner?:eek:

Does it do it in neutral? white smoke? Mine did it in drive and smoked a little(alot) dealer updated the soft ware and it stopped.

I had the software update done. Called the dealer and it had two codes in it from the block heater. Just have to make shure it will be below 30 or I cant plug it in.

Mine started doing this last friday night, It idles rough when warmed up. But if i just barely touch the fuel pedal it goes away, even though the revs dont come up any. Ill get it to the dealer someday.
