Mike,
First, take a deep breath, brother. Second, you seem to have forgotten one
little piece of information... what's the code,man?! The check engine light
is telling you SOMETHING. What is it?

I'll roll the dice... Bad 02 sensor?

Subject: Check Engine Light Hell.....

  I am totally confused. I bought my 89' 200tq two years ago and the check
  engine light has been coming on that entire time. I had the knock sensor
  retorqued, leads checked,everything!!!! I finally decided to get a new
  one and it took months to get it ( I ordered from somewhere not
  realizing it was on back order, and they sent me the wrong one first
  (which was also on backorder)). After my months of waiting I finally had
  it installed today. The car drove home better than ever! No check engine
  light and all of this power I've never felt before! It was like a dream
  come true. I got back in the car to go somewhere and the damn light is
  back on again, same as always!!! It comes on whenever the throttle is
  down 3/4 of the way. It doesn't matter if the engine is hot or cold,
  above or below 3000 RPM, under load, anything. Even while I'm parked and
  step on the gas more than 3/4 of the way it comes on. Someone please
  help me!!! I'm at the end of my rope. Five mechanics, two knock sensors,
  mega $$$$$$ on gas getting such good mileage=this car is going up for
  sale if I can't get this figured out by next week. It's not my first
  quattro and I've been understanding and patient all of my years of audi
  ownership; but this car is about to push me over the edge. Feeling the
  way it drove on the way home is the only thing that's keeping me hanging
  in there. I hope that someone can please help me ( I have checked
  manifold ground and air temp sensor as well).
