Thread: vac leak i think?

What is the serv no on your pcm? If its a 01+ PCM it could be the dreaded cat diagnostic test that makes you run +16.4... but thats only if you have a 01+ PCM and you run a rear o2 sim. Anything done to the rear o2 sensor?

Also, from my experience ... a really bad MAF tune can do that. I saw that after I cammed my car.

well i have a half ass maf job on my car until i get it retuned, i just have a basic lq4 bin on it and my inj. flow rate increased for the 65#'s, could i get this from running pig rich, my exhaust smells rich....?.....its only +16.4 once the car heats up.....if my LIM gaskets are leaking can i remove and reseal without ruining them? i got a 00 pcm with no rear o2 and codes deleted.
