My son’s 2003 Lightening is missing when cold and the computer says it is the #3 cylinder. So far we have changed the plug, swapped the COP, swapped the injector, cleaned the EGR valve, and changed IAC.
The truck only misses when cold and will stop missing within the first minute or so after being started. Normally by the time you back out of the driveway its ok. He needs to sell the truck but doesn’t want to sell it with a problem.
Any ideas on what the cause may be?
