I have a 2004 MC SS that just started having a problem where after the engine is up to temperature it has a miss. Well actually it feels like it quits and refires after about a quarter second delay. I am not getting a sevice engine soon light.

The car has about 100,000 miles and according to the parts store they can't pull any codes from the computer unless the engine lite is on. Any suggestions?

 

My first guess is the factory plugs should be changed. The original plugs are good for about 100,000 miles, then it's time to change them.

Stick with AC Delco plugs or NGK is OK. But absolutely NO BOSCH plugs.

And welcome to the forum.
