Which is causing check engine light to stay on causing misfire on cylinder #1 and then random misfire. The car hasn+t been able to be inspected in 2 years have had at 3 chevrolet dealerships and all can+t figure out issue . The 1st dealership said we have no idea what+s wrong with the car. The second dealership said the car needed #1 injector and injector harness and throttle body which was replaced didn+t even make it off the lot and check engine and traction control and ESC lights was flashing again they said might have cracked head car has been pressure tested doesn+t use water and doesn+t get hot. They are just trying to throw parts at it at my expense. The 3rd dealership which car is at now is telling me possible burnt valve causing all my issues with car said they did compression test and all cylinders have 170 pounds in all 4 cylinders which is not possible.

'takata recall' at start up , a loud noise comes from the left side of the engine compartment . As you drive it , there's a loud noise coming from engine compartment as you turn. Definitely a steering issue. Meanwhile, the ESC off, service traction and the service ESC warning sign illuminates . The check engine light flashes as the car misfires from cylinder 2. I have changed all spark plugs and the injector to cylinder 2 and the same issue happens. The vehicles has shut off on me as I came to a stop at a red light at an intersection. All these issues occur as your drive the car and go away sometimes, but never for good. This has been an ongoing problem for over a year now

While in motion car jerks and almost stalls. Rough idle again jerking and almost stalling. Service ESC / service traction /engine light come on. If car is not used for a few days, warning light will not come on. Then about 30 miles into drive lights come on and condition described above occur. This is a very dangerous condition.

Timing chain causing car to misfire and engine light on

Misfire cyl #1 and eng lt. With misfire code, attempted chev dealer warranty repair with removal of cyl head and replacemnt valves [the cheap fix instead of replacing cyl head, in retrospect I believe chev should have replaced the cyl head for a permanent repair, now the car is out of 100k powertrain warranty] but recurrence 22k miles later. I suspect a design flaw. Iternet shows many owners with same complaint. Traction control light continues to come off and on.

Vehicle was in motion at about 60 MPH on a highway and the rpms dropped drastically, the anti skid indicator light came on, the vehicle lost power temporarilly. I pulled over and slowed down and the car returned to normal. Same evening vehicle was in motion about 55 MPH on a highway when there was a loss of power, steering got sluggish,all indicatorlights on dash blinked on and off engine light came on and stayed on, anti skid indicator light came on, was knocking in motor and car would not accelerate over 20 MPH. Completed a diagnosis of the vehicle and a code p0068 was noted by diagnostics. P0068 the engine and transmission system is not performing as expected. An issue has been detected in the throttle control system that connects the accelerator pedal with the throttle and integrates features such as cruise control, traction control, stability control, and pre-crash systems. If the check engine light is flashing, a misfire condition has been detected. A misfire increases vehicle emissions and could damage the emission control system on the vehicle. Please reduce vehicle speed, avoid hard accelerations, avoid steep uphill grades, and reduce any cargo loads such as a trailer. If the vehicle is continually driven with the check engine light on, the emission controls might not work as well, the vehicle fuel economy might not be as good, and the engine might not run as smoothly. This could lead to future repairs
