My 2009 GMC Acadia Misfire
I'm having a problem with my 09 Acadia, after it runs for a good while it will sputter for
about 4-5 seconds and the odometer display lights will flash then it pops right back up
and will run fine for a while again. The check engine light cam on and when i read the
code all it says is misfire #3 cylinder. Could it just be a bad plug making it misfire every
now and then or do i have another issue? I was going to try a tune up but it looks like i
will have to pull the intake manifold to get to the plugs and coil packs.
