rough idle 2000 silverado

springerpup · 02-06-2007, 04:37 PM

I am experiencing rough idle after i start my truck. My engines revs for a few seconds, coughs and spits and almost dies, revs again, sputters, and repeats for the first minute or so after starting. I have the 4.8 V8 with 4WD. It also has a strange sympton on top of this, when i start driving and come to a stop sign, the engine will rev to 1000 rps for a second or two, then return to 500 and about 10 seconds later it repeats.
does anyone have any idea what the problem might be?
thanks for your help

My 99 chevy has the same type of issues and I havent figured it out yet, but one of my coworkers had the same problem with his 01 chevy (no codes) he changed the plugs and it quit.. I did the same but no luck for me..
