So my fiance has a 96 audi a4. Recently, 1 of her cats started rattling and went to shit. So I took it today and got the bad cat replaced. It also stopped up 1 of the mufflers from blowing out the cat, so the muffler was removed. (sounds much better with only 1 muffler) The car runs good and has lots of power compared to before BUT it has been having starting issues since the cat started rattling. Now it's still doing it.
You have to crank it for a long time to get it and it nearly dies due to flooding. You have to rev the engine to keep it running for a few, then it's ok.
I'm thinking the O2 sensors are contaminated from the stopped up exhaust. Does this sound right?
And we just had the car serviced for the ignition switch recall but I've heard a coil recall is coming. We checked the coil and it seems to be firing just fine.
Any other ideas or does it sound 99.9% likely that the O2s are done for?
