So I had my car tuned recently. Now I'm getting code after code. I'm getting p1400 for unauthorized software. Does that cause a cel? Now I'm getting u1134 and u1140 for the exhaust valves. Do they cause a light? I'm also getting p0125, p0430, p0219a. I think these last 3 are related. Any ideas? If I clear codes and start the car and drive for any amount of time the light stays off, but soon add I shut it off and restart it comes on immediately every time.
