I NEED HELP AS TO THE DIRECT PROBLEM IVE BEEN GOOGLING past 2 weeks....not understanding exactly what I need to replace on my 2009 Chevy aveo5 1.6L 4cly -
Unfortunately neither of the codes you have explains exactly what the problem is. One of the common items on all the codes is a problem with the Powertrain Control Module (PCM), but there are some tests that needs to be done to determine exactly what the problem is. You could either replace the PCM or have a shop do some test to diagnose the problem.
