Electrical problem
2006 Chevy Cobalt 4 cyl Two Wheel Drive Automatic 80,000 miles

I know that this is o2 heater for both 02s, have replaced with direct fit o2s, still have problem. Checked fuel pressure and think it is kind of high, flutters around 60 to 65 psi, car runs ok sometimes and bad alot also.
Did not have a card with me today but will be happy to pay for help, thank you!

follow the trouble trees try skipping the first 2 instructions on both trouble trees since they ask you too do a special that only very few scanners can do.you will need a scan tool that can read engine data stream like o2 readings etc.let me know what you find.

Thank you for the help. This was one or the worst jobs I have had in the shop to date. One of my guys put the 02 on this car about a month ago, come to find out that napa sent one for a 2.0, not a 2.2, it will fit but the wires are in the wrong location, what luck.
Thanks again, Steve.
