[QUOTE="Makobra, post: 16263322, member: 193575"] Question: when it starts running like crap if you floor it does it get over itself and rev good? If yes then I think you've got a bad 02 sensor. its perfect at startup right? then the sensor heats up and the pcm starts trying to use it but the sensor is fragged so the readings are bad so the computer probably tells the injectors and coils to do the wrong stuff. your front O2 sensors do this (before the cats) so I would replace them and see what happens. the same thing happened with my 94 f150 with a 302, it would stumble and when i floored it the truck would run like a scalded dog. it was very strange but a new 02 sensor fixed her right up.
