Where can i go to have a diagnostic run on the car. I recently installed the DC header and the CEL came on. I did th antifouler but its still on. Im thinking its the O2 sensor on the header but i just wanna make sure so i can fix it. Thanks.

 

I would go to autozone.... Free reading...

I'd bet you it's still the 2nd O2 sensor on the spipe.... The first one shouldn't throw a CEL unless you REALLY did something weird.

Are you sure you're running two antifoulers and have the one closest to the spipe not drilled out and the one furthest away drilled to the neccesary spec?

Just checking.

You can take it to AutoZone, Western Auto or Advance Auto Parts. Each of them will loan you a scanner that will let you read the code. The sensor on the header is your A/F sensor, you would know if it was bad 'cause your car would run like total sh**!

 

my bro took the a/f sensor and soaked it in wd40. If theres a leak in the A/F sensor bung would it throw a CEL.

 

No.... the one on the spipe on my car was superloose once and I didn't throw a cel... just heard it rattling....

Check your antifouler setup again... reset your ECU one more time and cross your fingers...
