ususally a flashing check engine light indicates a misfire, best to have the codes check first and see which cylinders are misfiring, could be something as simple as spark plugs or a loose vaccum hose, same with stability trac, module needs to be scanned for codes first

So read the codes and everything and it came up P0 300 which is a general misfire went through switch coils two different cylinders coils are okay went through disconnected injectors one at a time until engine stuttered. Cylinder 7 no change when disconnected ordered fuel injector we'll see if cures problem


p0300 indicate random cylinder misfire, usually the cause is 2 or more cylinders misfiring, if you know someone with a higher end scanner that does live data you can actually see which cylinders are misfiring in real time (makes things a lot easier).

The biggest problem with cylinder 7. Cylinder 2 had an occasional misfire so replacing both but definitely not as bad as number 7

And we were looking at it live as it was doing it with the scanner.

Two new fuel injectors on cylinder 2 and cylinder 7 all new plug wires and plugs and new coil pack on 7 problem solved runs great

Mine was a chewed through wire on the #2 coil pak(the red wire), stabiltrak and traction lights, DIC indication of both off, flashing check engine light, rough idle hard 1-2 shift.Repaired the connection and all is good so far.
