I've tried finding symptoms in other forums with out prevail. Was driving along and suddenly felt a small jerk almost like a misfire but then lost tack, the stabilitrak light came on and would not rev over 5k. So brought it home let it sit then tried it again and it idled fine for 5 minutes or so then same thing. Ran the codes and replaced the crank position sensor, ecu, engine harness, cam sensors with nothing helping. Took it to my local Chevy dealer to have the ecu replaced( that is what they thought it was as well) and $460 later same problem and they wanted to start tearing the motor down so I brought it back home. I was hoping someone may have had similar symptoms or has heared of a fix for this issue.
