my exaust stinks really bad like fuel, and my car doesnt seem to have as much balls as it used to have, i just added a cold air intake hoping it would give me some more horsies, but no, my tstat seems to be working fine, do i maybe have plugged cats, also after long full throttle romps i get a c/e light for about 11 seconds, then it goes away, maybe plugged cats? whats the talk of this acp somthing sensor i heard about in the other posts?

did you run the codes?

If the electronic engine control system is operating correctly with the inputs from all the sensors, the engine cannot run rich or lean. Only if there is a problem with the inputs (sensors) can this happen. The CHECK ENGINE light is telling you that there is a problem. You just need to ask the EEC what the problem is by running the KOEO test. It is very simple and takes no more than a short jumper wire and the ignition key. Learn how to rear the codes here. For the engine to truly run rich, the oxygen sensor(s) must not be providing the correct feedback, but don't guess - read the codes. That site gives you the test procedure and the links to the code descriptions.

Inaccurate inputs from the sensors. Just because it isn't generating a code doesn't mean that an old sensor can't miss the target bit. The bottom line is the O2 sensors. If they are reading correctly, the EEC will adjust the fuel as necessary to get the proper mixture. That means that the most likely culprits are the O2 sensors. They should be replaced at 60,000 mile intervals since they get "tired" and don't switch from rich to lean as quickly as they should. This results in lower performance, lower fuel economy and higher emissions.
hmmmm. I got 2 brand new Bosch 02's a few mos. back when I had my 60K. It wasn't a few weeks later that I noticed a loss in mpg 
(about 2 mile to a gallon) I wonder why?
My cats were removed right before I replaced my 02's, could this have caused too much heat and "burnt" my 02's? (I have neard of extensions you can buy to pull the 02 sensor back some to protect it)
