Asked by dtaylor Jul 29, 2011 at 10:03 PM about the 2008 Chevrolet Silverado 1500 LT1 Crew Cab

Question type: Maintenance & Repair

I have a 08 Silverado 4.8L. The check engine light came on. I took it to Auto Zone. They said cylinder #4 is misfiring. Probable cause is faulty spark plug, wire or core. I have all the items replaced, and the light came back on and Im getting the same code after replacing everything new. Does anyone out there know what the problem may be. The truck only has 78K on it and runs like a top, but I hate seeing that light on.

unhook your battery,eather side for about 10 minutes,it will clear the code from computer and light will go out.

Ill give it a try. I had Auto Zone clear the code with the computer, and it stayed off for a day, then came back on.

take it to a dealership and have them check the engine if the 4th cylinder is missing there may be a problem with the engine if it's under 100k they should replace it for you they did on my cobalt at 76k

does it sound rough when it runs that would confirm a missfire as a probability it could be causted by a mistiming

I drive 100 miles per day. My 4.8 dropped cylinder 4 at 116000 miles. Ran great with a little rough idle once in a while. Dealer serviced regularly.
