Default 1999 A8 idling at lower RPMs, loss of performance

I've got a rather strange problem:

Car starts fine at idles at one notch below the 1000rpm on the tacho. Normal.

I put it in Drive, and it gently starts creeping along at 5-7mph, unlike the normal vigorous 10mph speed.

Put it back in Park, it idles TWO notches below the 1000rpm mark.

While driving, when I take my foot off the gas, the car seems eager to downshift to 1st and then eventually slows to a 5-10mph crawl. Definitely not normal.


The only known issue is the ABS light - been coming on and off for the past several months: at least two of the speed sensors are bad, but could they really conspire to create a weird set of problems like that?

Also been getting faint whiff of raw gas inside the cabin a couple times, but I dunno if thats just paranoia or......? Could the fuel pump (or whatever) be losing pressure, which is resulting in a loss in performance and generally lazy behaviour, including idling at unusually low RPMs?

(Truthfully, I'm getting ready to throw in the towel)


Puuhlease help!
