I was on my way up to ESU, and my cel came on. there was no immediate problem, BUT i pulled over and used my code reader (was in the glove box). I got P1151.
The car was idling high as well. I turned it off, and back on and ran the reader again. then erased the code. The idle came back down.
I drove the last 30 miles and it didn't come back.
Does this mean I need to replace my 02 or not? I get crappy mileage (17mpg) and and once and a while i get lean codes in both banks.
could this be the problem?
