My bad, first time around on the forum. Can't find original post because I had so many.

Prob: My car is an 86 4 cyl that someone swapped a 302 into. Originally the car had an AOD that I swapped to a T5. When the car would hit approx 3000 rpm's, it would start spitting and sputtering until I slowed down or shifted gears and then would be fine until the next time you hit 3000 rpm's.
I started with the fuel pressure which would drop when the prob started so I replaced fuel pump (mechanical). No good. Checked timing, could not even see the timing marks (posted this one). Removed dist and reinstalled got timing set prob still there. Replaced plugs and wires (still there). Replaced dist cap, rotor, (still there). Back to a possible fuel prob. Rebuilt carb. Replaced fuel lines. (No good) Checked all the vac lines (no good). I had posts all through this period I just can't remember them all. I had one suggestion that the tfi module on the side of the dist may be bad (had not thought of that one) so I replaced it. (nope) Finally a buddy said that the tfi module is used on fuel injected cars. Theres a post, folks agreed with this statement. Swapped out dist today and got the timing set and lo and behold that fixed it. I went the LONG way around but finally got there. I wished I could remember all the posts but there was to many. Been at this for about 2 months glad to be done with it. Anyway, thanks and I hope this is what ya'll are looking for.
 
in the future, you can click on your username and look up your posts and threads started by yourself.

im glad to hear it is running well. and good that you posted your findings - people often dont and we dont know what worked and what didnt.

nice work!
 
Does the new dist have a TFI module on it? If not you did some re-wiring and the wiring may have been bad. My guess is that the PIP sensor in the dist. was the problem all along. Did you ever pull codes to see what the computer says? Thank you for posting your fix and all the steps you went through. Throwing parts at these EFI motors is very expensive. Much of it can be saved with proper diagnosis. I had to learn that the hard way too. Cost me alot.
