I bought a used 2009 chevy Cobalt 2 years ago in 2017 with 119k miles. It has been nothing but a headache with things going wrong! the biggest issue is the code p2135 that sends the car into reduced engine power and the engine shakes violently. This is very scary especially�with 3 young boys in the car with me. I have replaced the entire throttle body, ecm, accelerator pedal assembly with new sensor, crankshaft positioning sensor, camshaft sensors, spark plugs and spark plug wires. After all these things I am out of ideas on�why this keeps happening in but all those new parts have not fixed the problem that keeps occurring. Please tell me there is a recall or you can at least tell me what the problem is. I have read many forums about people with this same issue.
