sn-95 exhaust leak

If the leak is at the collecter it can draw in fresh air and trick your o2 sensor into thinking it is runing lean. Also check your o2 sensor plugs for wires that may have been pulled out during disasembly . one more thing when you are checking your 02 plugs and fixing the leak take off both terminals on the battery to clear the ECU.

^^^^^^^^^^^^^^^Yup, it's probably running rich now. notice a change in fuel mileage?

millage has dropped but you can smell it running rich but head4ers and h-pipe will be in tomorrow but what do yall think about the tps could it be bad

IAC valve?

I would fix that exhaust leak first since you know that is a problem. clean the IAC valve and go from there. maybe clean the mass air flow as well.

You didn't read what these two said below did you?

Here: RE-read it.

Fix the leak, and change the O2's while you're there.You're problem 99% most likely the leak, causing fouled readings in teh O2s, reading lean, so it's tossing fuel at it. New O2s just for added insurance.
