Long story... Fox setup, was an sc build now n/a. When boosted it did not like wot once it was warmed up. Now n/a with pro m maf, #30 accel injectors, tps, dist, all replaced and new car acts like it is shut off at wot. all of the time. A1000 pump @43 psi as accel calls for. Have played with timing and fuel pressure and lots of other stuff as well pressure stays good when it acts up. Wondering where to look next? Setup is currently in my '68 but as I said it did the same thing in the fox.

Might sound dumb to ask but have you replaced the plugs and wires? Especially since converting back from SC?Originally posted by PGreenCobraOriginally posted by Trip McNeelyComment

I have replaced the dist once when it was acting up boosted. Just warrantied it last week to double check. Since going n/a new plugs and wires with appropriate heat range for n/a. May swap coil but I have heard they are bad or they are not.. Car runs the same on msd or stock ignition. Have not yet replaced the map (Baro) sensor. Still scratching my head. Wondering if a shop could figure it out on the Dyno? Most of the electronics have been replaced/changed since the swap. Still the same scenario. Drove the car on the hwy a few weeks ago and for about 10 mins of an hour cruise it totally smoothed out sounded great and ran way better, then back to normal (bad). I have pulled the ecu apart to look for burnt grounds and swollen caps but it looks fine. Wondering about open/closed loop operation? Ugh... Thinking about going carb'd and forgetting this..Comment

If the computer can't figure it out after after driving it for a while and you haven't continued to reset it and what not, I'd say get it tuned.Comment
