Asked by Shawn Aug 08, 2021 at 01:11 PM about the 2001 GMC Yukon SLT 4WD

Question type: Maintenance & Repair

Ok i got cylinder #7 misfiring. She
has 334,000 miles and is still
running good but I hate when it
starts misfiring. Anybody with any
good tips for the yukon even if they
have nothing to do with misfiring. I
want to hear from ya cause I'll
probably be getting spark plugs,
wires and a couple coils soon

If the plugs and coils don't do it you should check the compression to see if #7 is weak.
