Been having issues with my car, "check engine light" turns on, cylinder one misfire, car kind of shaking at idle. Also, traction control lights randomly turns on saying service ESC and service traction in a message. When the traction control lights turns on my car shifts hard going to second gear (automatic transmission). Any help or suggestion will be helpful just need this car fix, ASAP.

If you have a constant misfire see if you have spark on cylinder one if not bad coil pack. For the traction control light you will have to have it scanned for codes with a professional scan tool. Write down the exact code numbers not code descriptions. Let me know what they are.

The code is P0301 I switch my ignition coil around and deleted code and after a few minutes came back up, and now that I remember it started doing that right after I once pump flex fuel on my car.

Sounds like the fuel you got but that would cause miss fires on all the cylinders.

When I switched the coils around, the mis fire still on cylinder 1 and now that you mention it, I did get a random mire fire as well when it started with cylinder 1 but that went away after a week and forgot about it

Inducing smoke in the Intake is the best way.

I don't like cylinder 1 compression and that one is the one setting the code. If you swapped the coil spark plug and fuel injector and your getting a injector pulse to that injector. Then the only thing left is the compression/mechical issue.

Did you have this problem and the throttle body replacement fix it, or did you just clean it?

My Traction Control Light comes on and immediately the transmission starts shifting Hard, shortly after that, the check engine light comes on. We had the transmission checked by a trasmission shop, they found nothing wrong with the transmission. He said it could be some kind of sensor. If its the Traction Control sensor, can we just disable the system.

There is an issue with some debris getting into the camshaft actuator solenoids. They have screens to protect but will occasionally get plugged. Frequent oil changes will help. Pull codes and find where to look.

Your going to have to get your codes read that's the starting point. You will probably not be able to get the traction codes with a diyer scan tool. Let me know the exact code numbers you have not code descriptions.
