2000 sierra 4.8L misfire issue
i have a 2000 gmc sierra with the 4.8L V8 and for some reason i can't figure out it misfires. it only happens when i've been driving for awhile and start it back up it misfires. It goes away after driving for about 30 seconds. but its really annoying and makes the knock sensor go off. if anyone has a solution or and idea please let me know cause i have no idea.
