Question about 1999 GMC Yukon Denali
Locate the coil pack.... pull one spark plug wire at a time... any change in how the motor runs ... replace it and move to the next wire. if you pull a spark plug wire and there is no change you have likely located the problem.
a couple things... if the check engine light is on stop into autozone and have them read the codes (free) also another possibility is a plugged catylitic converter.
