95 millenia 2.5 reaches n.o.t. and goes to crap
Howdy! New to the forum, but I've had mazdas for quite some time my other car is a 79 rex. My problem is that the 95 millenia runs fine until it hits normal operating temp. then it quits accelerating. It doesn't die and if you give it as little pedal as possible, it will accelerate very slowly. In park or neutral it will idle ok but if you give it gas slowly it will stumble up to about 2k then rev normally from there up. If you give it pedal fast it stumbles and doesn't change rpms at all. I'm not getting any check engine light, and my gauges read normal. Here's what I've done so far; air cleaner, fixed vaccum leak, checked intake hose for leaks and prayed about it. I would replace the tps then the mas then the engine coolant sensor then the distributor but shortly this would cost more than the car is worth. Has anyone had these problems or know how to fix it?

Had a older 626 4 cyl that did the same thing and turned out to be a clogged catalytic converter. Repaired it by removing it and shaving off the top (engine side) 1/2 inch of honeycomb with a ceramic drill bit. Ran great and still passed emissions afterward.
