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.


I am having the same issue with the Stabilitrak. The light came on it is idling real rough and there is a ticking noise. I have searched and searched and this seems to be a common problem I have contacted a lawyer who represented the Dex Cool case back in 2008. I need help getting this thing going so please contact me on here. I had my motor rebuilt in 2015 because I lost compression on number 7 cylinder I spent over $3,000 having the motor rebuilt. Let's get this thing going because GM is aware of this problem and has done nothing to help resolve it so the more people we get the better case we will have. I cannot afford to have my motor rebuilt every few years and I am not going to pay to have a motor rebuilt that only has 27,000 miles on it.

Am having same issue with my 2012 Silverado. I can disconnect the battery and after re connecting it when I start the truck all seems normal until I put it I drive and the stabilitrack, check engine light come on and the engine runs very rough. The truck is currently at the local chevy dealer where I bought it in 2012. They basicly want to rebuild the engine but I can’t afford the expense. Seems to me that if every thing resets after disconnecting the battery there mst be a simple solution with out replacing everything and hoping it solves the problem.

I replaced the plugs in mine and so far it's been ok but I know there's more to it than just the plugs. Email me at I've talked to a lawyer so get in touch with me


I had Stabilitrak and traction control lights along with flashing check engine. The idle was rough. Problem is one of the variable lifters is stuck. Pulled the valve cover and one wasn't working. Costly job to repair.

Hey, I recently had my 08 Silverado ls having bad shifts like, only shifting if I take the foot off the the gas and hit it again. The power is too low doesn't go over 60miles and blinks the check engine and traction control lamps every time I try to overtake. Can somebody help please?.

exact problem as stated in the title and had ignition coil 7, spark plugs and plug wires replace now all is back to normal

My car (2015 Traverse) did this same thing today for the second time in 2 weeks. While accelerating (maybe 40mph at that point) the stability/traction control flashes and states that its turning on and off, while the check engine light flashes. Power is obviously lost and the car is no longer accelerating/is acting funny. Kind of scary, especially with my kids in the vehicle! Both episodes lasted maybe 1 minute total, then the car is fine. I took it in to our certified dealership and they couldnt find the issue. They said 1 cylinder showed a misfire, but they arent sure why. They did look at the spark plugs and said those were fine. I did call GM corporate because I noticed this seems to be a common GM issue......anyone have a REAL fix for this issue?!
