After replacing the spark plugs and #2 ign. coil and clearing the code the check engine light came back on. I'v since cleared the engine several times and after a 30 to 60 mile drive the light comes back on. It runs rough at idle. Has any one had this problem?

Well when the engine is cold it will run fine, but when it warms up it wants to stall when im coming to a stop. But when i rev it up a bit,it will run ok for a while. Ive changed the fuel filter and the fuel pump,changed the cam sensors and changed the plugs to no avail. Please a response would be greatly appreciated

Well the sensor above the gas tank to prevent overpressure is loose. Well, it has always been loose. When Chevy built the truck they forgot to install the harness to hold it. The wires have since snapped and the check engine has come and stayed on. Taking it to the dealership and was told there is supposed to be a harness there. They will fix it but will cost me for Chevy's over site.

I love the truck but I've only had it for around 9 months and my service engine light has come on three times for the same problem. When i take it to autozone to get it checked they tell me that its from lean gas and ask me if i filled my gas up recently. Its off right now but for how long?......nobody knows!

Update from Jul 30, 2010: After going to autozone a couple of times and getting the same code from their computer I decided to look up on the internet myself what the code meant and sure enough it ended up being an oxygen sensor. I replaced the oxygen sensor myself and havent had a problem since.
