Hi group, once again my used aveo5 is not making me happy. I had a bad battery and replaced it but took it for a smog check the next day I failed with obdii not ready found out the car needs drive cycles to ready everything but really having a problem with HCAT and Catalyst not sure what to do...
Has anyone had this issue I have 86k on this car... I was trying to replace the upstream but it's on too tight need to have a mechanic do it since I've already broken two bolts off (different areas) and went through the drama of drilling out and adding a helicoil.
Could really use your help... Thanks in advance
