2011 GMC Acadia misfire at idle
Asked by richardkook Oct 01, 2014 at 11:03 PM about the 2011 GMC Acadia SL FWD
Question type: Maintenance & Repair
I have a 2011 GMC Acadia that misfires on cylinder #3. I have had diagnostics done,
which lead me to replace the plugs and intake gasket. This did not correct the problem. I
am now going through the process of elimination. My next move will be to replace the coil
pack on that cylinder. Any advise would be helpful.

Unless you have over 100,000 miles it should still be under GM's drivetrain warranty.
I had a similar issue with an Acadia under warranty, the dealer could never find an error code (2 incidents) so I tried a different brand of gasoline, never had the problem since.
What brand gas you use ? I’ve been using regular 87 in mine (under warranty still) & it’s been missing. However, it didn’t do that before at all. We’ve only had it going on a week. Just wondering if that’s my problem.
