Little help :)
Hey guys quick question.
First of all i have a 1999.5 Audi a4 I am buying a cat delete and exhaust for it within the next week. I have been having a check engine light issue that comes on about once a week, and its the same code every time. It say catalyst below threshold. I was told this was because my o2 sensor was bad but come to find out i had it looked at and they said it was fine... So my question is when i put that cat delete and exhaust on will i have a check engine light on all the time? or will it just keep coming on if i cannot figure out the problem with the code that keeps coming up? And yes the cat delete has both ports for the o2 sensors.
INPUT PLEASE and thank you

Once you remove the cat, your CEL will be on all the time unless you do the Anti-Fouler trick. Do a search, here, or even google it. Basically, you know two "anti-foulers", drill a larger hole in one so the O2 sensor will fit, screw the one you drilled into the on that's not drilled, put it in the down stream O2 bung, install O2 sensor, and marvel how the 5 dollar trick prevents future CELs. Tried and true, I have a test pipe, and no CEL (and had the same CEL code before I installed the TP and anti foulers.
