well lets just start with everything i have replaced. fuel and air filter, plugs wires, cap, rotor, the basics....... engine is running like crap, rough idle, jerky shift points while driving, push the pedal and no go. engine temp is a lot higher than normal.also found oil coming from out of the crankcase relief tube and going into the throttle body, check engine light comes on every once in a while when it is really running bad, but goes back off. im thinking it may be the catalytic converters are blocked.but im not a mechanic. the engine is a 302 ci fuel injected with 110xxx miles nothing overhauled or replaced.the trans is auto e4od and i have had a problem with it yet:embarassed: but i know the time is coming for another backyard rebuild, i heard that particular trans doubles as a boat anchor. if anybody has any insight let me know.
