My96StangCA

Let me start off, I am not a novice to working on cars, and I can't find any mechanic who has heard of this issue so I am open to all suggestions. I have a 1996 Mustang GT I have done other Modifications to it but have tried several cambinations in order to fix this issue, nothing has worked. Every time I put a cold air intake on my stang, my O2 senors fails. From what I understand it runs too lean, the computer doesn't adjust and the sensors burn out. I have bought and tried a bigger throttle body and plenum, as well as a engine tuner. neither helps the problem. The only other thing I can think of is taking the car in and having the computer re-tuned with the cold air on or simply getting a new computer. Also would a adjustable fuel regulator work to solve this? just throwing out an idea. Please help. Any information is a plus.

I would start looking at the MAF.

Welcome to MF's..

Have you considered getting it dyno tuned.

Is the cold air kit relocating the MAF to a non stock location? Maybe to close to the air filter or too far. Are you only getting codes for your 02 sensors?

Try cleaning the MAF wire with some alcohol wipes or something that will remove grime.
Might help things.

The Cold Air Kit that I tried does...yes it does move the mass air flow sensor. I have tried cleaning it and getting some of the grim off of it. I don't know if the shop that tried installing a kit moved it as well or what. IF that is the case, what would cure this issue. Because when the codes come up their just the running lean in left bank and right bank codes. I forget the actual codes because it's been a while.
