Hello all,
I hope that you can help me. I just replaced the catalytic converters and 02 sensors on my mother in-laws '89 Cougar LS. Now the idle is a little rough and when you put it in gear it gets worse. It ran fine before the work was done. It also has had the CO on in the dash for some time now. Do you guys and gals know of things that I can check out first?? The timing is spot on, has new plug wires and the auto trans was just serviced. Thank you for any help that you can give me.
Dave
