2011 HHR Timing Chain and code P0300
Have been working on this for a few months now. My 2011 HHR 2.2LT has had new timing chain, sprockets, bolts, water pump, coils, injectors, MAF sensor, Cam sensor, gaskets, you name it done. It is still running great at 50 to 55 not a miss but as soon as you stop it won't idle. It stalls, jumps, and dies. What suggestions can you offer? Thank you. P0300 is the only code. It also has check engine light that says service ESC and Traction Control.
