I had an 8 year old MAF, so i replaced it... and after the replace i still have these codes


P1116
P1128
P0134

So, i think i have a leak somewhere and a dead o2 sensor? Any other ideas?

 

no1 with any input?

 

Nobody has any input because the answers can be found in the FAQ.

I'd start with checking the connection to your pre-cat 02 sensor... But that's just me. [8D]

 

i always thought losing an O2 sensor would cause my car to run rich? and a leak in the air system to cause it to run lean because of the un-accounted for air?

 

Check for loose connections on the O2 sensor. If the problem doesn't go away, check for vacuum leaks. It usually has to be a fairly big one to throw a code.

 

are you clearing the codes and then running codes again after a driving cycle?

 

yeah i have cleared the codes and ran many cycles, the car seems very sluggish, so thats why i was thinking vacuum leak.
