Hi guys I recently bought a 06 Chevy cobalt lsj 2.0 drove fine for a couple days then went to crap .. its idling weird wanting to die, it stalls while driving, getting poor gas mileage and is running rich. The computer says p0017 crank and cam correlation code timing but the motor was just redone and I checked the chain and its right. Replaced the 02 sensor, crank and cam sensor, MAF sensor, and fuel filter and nothing. Still not running right when it starts to get hot, please help!!!!!!!!
