Recently in my 2007 Cobalt when sitting in park my service traction control would come on.. If I restarted the car it turned off... Today it came on automatically and now my check engine light is on. I am very nervous and hoping someone can help me with some answers... I don't have much money and I just am going back to work Monday after being out for a week after having my appendix removed... Help?!?!?!

 

What DTC's are stored in the modules?

 

I'm not sure I don't know too much about cars but my dad did a reading on it and said it was P0302 cylinder 2 misfire... Does anyone know how much that'll cost to repair and how soon I need to get it done?

 

Does it do this all the time? I'd suggest remove the plug, see what it looks like. If it is misfire the plug will have black soot on it. Another thing, swap plug wires with another cylinder. If the problem dosen't follow it will need a little more research.
