taylor_hindman To get the rear off you have to remove the solenoid pack off the back side of the upper intake pipe and then remove the solenoid and bracket off the fire wall and then you can finagle it out of the back through the top. The front is easy. Remove the front intercooler will make it easier to get to the upper exhaust manifold bolts. If you knock them out you won't get a code for it or at least I haven't yet and I've been driving it like this for the past year.

nivram I to have a accelerating problem with the AC turned on, but when I am am in second gear or third, the motor just falls flat or hesitates till I slowly reach 2800 RPM and then it starts to move. Could this be the TPS? Throttle position sensor? If so how do you set it to the right position. Its a ----- to get to.
The car runs good without the AC compressor turned on. I don't believe this is normal.

Clayton88 I have a 2001 Mazda Millenia with similar problems. I was wondering if you ever got yours to accelerate like normal again? Did you cut the Cats off? If so, did that mess with the 02 sensors?

Subzero2012 If you don't get any codes then it's the CaTs

mazda-fla Pull the codes and post them. That would be the first place to start.
