Ok thanks brother.

Ok replaced both upstream O2's and let it run for about 10 minutes and check engine light is still on. So I'm banking on I need to clear the codes. Any sneaky ways besides disconnecting the battery? I have heard you can run 50 miles and the computer will run a new diagnostic on it but with 35's...

Whole process took 15minutes. Getting the harness off is the hardest part (little flat head between detent after pressing it down) spreads open easy. Now for the moment of truth, starting it and seeing if the error codes return!!!!

The 23138 and 23139 I have received and currently soaking PB Blaster before attempting the removal. I didn't see a diagram of which one goes where, are the connectors the tell all or do they go into specific ports? I.E. front or rear.

Thanks a million brother!!
