92 plymouth idles wont run

i have a 92 plymouth grand voyager that idles but when you give it gas it misses bad. fuel comes out the exast. have put new timing chain and gear on,changed the main computer, did a tuneup on it, put water temp senson on,
new throttle body,checked fuel pressure, checked coil pack no codes on computer can anybody think of something that may make it run rought when you give it gas thanks

Did you change the timing belt to fix this problem or did you change the belt and gear and then this problem showed up. It sounds like the timing is off. There may be a problem with the valves.

Did you do a compression check?

Does exaust come out of the throttle body? If so I'd guess timing or valves.

Are you sure the fuel is good?

I'm told it is very rare for gas to make it all the way out tail pipe.

fuel coming out the tail pipe!? think 02 sensor.
