2002 GMC Yukon XL 1500 SLE 5.3L Misfire, MIL Lamp on
Thanks in advance for all your help! I have this truck that will only misfire for about five seconds on a hot soak condition, 1 out of five times. When the problem occurs all even bank cyls. experience misfires. When this is happening cyl. #6 counts three time...
