2000 GT issues
It seems like there is always something wrong with my car, brakes, suspension noises, rattles, you name it. Towards the end of last year my check engine light came on and the codes showed all four O2 sensors were bad.
It seemed unlikely that this was the case but we couldn't find anything else so eventually replaced them all since it was around 75k anyway. The light stayed off for about a week and came back on with 5 codes, something about the sensor heater circuits and something else. It then went off and stayed off up until a few weeks ago, now there's only 2 codes.
Anyway, lately it seems like there's been a ticking. Last weekend it seemed to have gotten much louder and my rpm's would bounce between 500 and 1k sitting idle and will sometimes die shifting into gear. It's always had a problem occasionally when you shift it into gear the rpm's will go way down then rev up.
We took the passenger exhaust loose to get to the sensor, could this noise be an exhaust leak? Also any ideas what's causing those codes?
Thanks

I sprayed out my iac with some fuel system cleaner. The rpm's seem more stable when putting it in reverse or drive, but I wasn't able to take it for a drive.
I think the noise may be the exhaust. It's pretty loud if you get down by the wheel well. Won't hurt to get under there and check it out tomorrow... assuming I can find a swivel to get up in there.

My '01 GT makes the noise too. '00 GT did the noise tend to go away as the engine warmed up? Or did it stay constant even after it warmed up? I thought that as the engine heated up it should seal up the leak, thats why I didn't think I had an exhaust leak, because the noise stays. Also my car does the rev up and down thing too, did anyone ever figure out what that was?
