First off i apologize if there has already been a thread on this. I wasn't able to find it. But I have a 07 2.2 auto cobalt. I'll fill you guys inn on where it all.started. I took the car to a shop because it needed a new transmission. They put one in and ever since I got the car bad I've had nothing but trouble. It ran perfectly fine before it needed the transmission.i got it back and it had no power and was misfiring all over the place. Found out the line going to the solenoid by the motor coming from under the car had been snapped off. I fixed that and I got the power back but the car continued to shift hard and it had a terrible cold start where I would have to start it 5 times to get out of the driveway.today I cleaned out the maf and checked the solenoid and everything looks good. Put it all back together and it runs great now. I went from having multiple issues to just one. Now when I go to take off the car stutters in first gear around 2200rpm. Sounds like the fuel is getting cut off for some reason. Any ideas as to what could cause that. Could they have snapped or broken a wire somewhere or is it a sensor? I know they had to replace the wires going to the speed sensor in the transmission because they had snapped those. Any help would be greatly appreciated. Just wanna get my car back to running how it was.
