Well this is what i do know,
My car runs good when i first start to drive it, but about ten minutes into driving, the car doesnt perform the same, ill try to accelerate and it will for a second but then the motor makes a lower tone and the car and rpms wont continue to climb the same.This happens in any gear at any rpm. Ive checked the imrc while warm in park and it always opens up? Im also religous about seafoamin and fuel system cleaners, so i dont think it would be a clogged cat, or injectors.Also im not sure if this has anything to do with the problem but sometimes ill nail it and it could be at 3000 rpms and the tranny wont downshift, it just slowly climbs in the same gear?Ive had trannys go out on me in the past(3 times, not on a cougar)and i always seem to know when it happens, that may be the case hear but i dont think it is. ANY AND ALL INFO IS GREATLY APPRECIATED!!
