hey guys,
i own a 05 cobalt ls, standard, 2.2 ecotech. when i went to start the car the engine had a loud heavy vibration, shifted into 1st and the car was extremely slow. restarted the car and it was fine. couple days later i started the car and it just stalled out. restarted it and it was fine, happens close to once a day now. theres no check engine light, only when the car starts up with that heavy engine vibration. havnt done anything to diagnose the problem yet, wanted to get some ideas first. im thinkin maybe some sensor is messed up.
please help
thankyou

Is check engine or equivalent light on while it does run? If so there's a code reading but before that if it will run for a little bit for you, take a look at the lower pulley of belt system (big one) which is a harmonic balancer which may be coming apart and shouldn't be driven if you see that wobble. Not sure if that common to this car but it does happen,
