My Daughter has a 2007 cobalt 2.2. Yesterday she put gas in the car and went to start but the car would not shift into gear. Tried reverse and drive a few times and it finally went into gear. Less than a mile down the road, car died once accelerating past 30 to 40 mph. Service traction indication light came on as well. I drove the car back home staying around 30 mph. Tested again today. Car starts but when cold you hear some knocking sound intially and then car idle levels off and idles normal with no noticeable noise. Check engine light is still on. Test drove the car today and again for me once I hit about 40 mph the service traction indicator comes on. Car tries to die unless you let off the gas. After that I also notice that as car shifts gear it jerks like the transmission has an issue. The car has a hard time getting up to 50 mph. Should easily accelerate to 50 mph easily but you can tell something is wrong. Ive looked on some other forums and some say it could be ABS/Speed sensor, the camshaft sensor, crankshaft sensor, some sensor in the tranny itself, clogged fuel filter, timing belt or various combinations. I will have to take the car to get diagnosed. In this case most are recommending taking to the dealership as guessing at this could be very expensive. Others have said, some or all of these were done and issues still remained. If anyone has experienced this, please let me know and if you were able to fix the issue.
