2004 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 94000 miles
I replaced the catalytic converter on my Trailblazer, now I have a check engine light coming on. I had an autoparts store check it out and they said it was either a catalytic problem or a fuel cap. I checked the fuel cap and it was good. Could the O2 sensors be bad? I read a few of your answers and saw a lot of problems with the MAF sensor but I can not seem to find that in my chilton book for the trailblazer. I also unbolted to the battery in hopes it would relearn the pressures with the new catalytic converter. Whats wrong?
have the same problem?
