2006 Pontiac Grand Prix

Asked by sherylann72 Nov 09, 2020 at 04:54 PM about the 2006 Pontiac Grand Prix Base

Question type: Maintenance & Repair

Car starts but it starts misfiring.  Im getting the P0300 code - Random
misfire.  Ive have the ICM swapped out, new plugs, wires, and ignition coils.  
It was running good for awhile after I got it repaired, but now its back to the
same old misbehavior. I cant drive it because of the heavy misfiring. Anyone
else ever have this issue? What is a possible route to go to fix it again.. this
will be my last attempt at it.
