Been getting the CEL for a while. Finally pulled the codes last week.
Bank 1 lean...o2 sensor slow reporting...P1131
From what I read in the search & at FlatRateTech.com it's the upstream o2 sensor of a UIM gasket leak.
I'm gonna try the o2 sensor 1st...
Anyone have any words of advice before I start this job? I know I can get the sensor tool from AutoZone, but wondering if there's anything else that will make the job easier.
I went to get a new sticker this morning and the guy said he couldn't get it to test. The exhaust wouldn't register on the machine. He tried three times.
I'm pretty aggravated right now. I just want this done and not have to deal anymore.
Thanx for any advice!
Rob
