i had a similar issue with the engine popping and such...i found a wire(think it was purple) that went to the TFI and it had 12v when it wasnt suppose to. so we cut it (per thread on classic) and now it revs til cows come home...before it would spit and sputter round 3k or more. as a matter of fact, i think i swap fuel pumps thinking it was starving...but that wire fixed it
