perplexed, bout to give up...
T78, 550/1600(cleaned/new), stock reman with 30 to 40k miles, recently installed jacobs rotary pack. after tackling a couple of problems and fixing them im now perplexed and about to give up with the latest one. i have spark, i have fuel, spark plug wires, coils, crank position sensors, igniter, map sensor all with in spec. spark plugs, well about 10 used ones, not bad, not new. compression is not great but not bad...
car wont idle for crap and has bad break up/missing in anything i think above 5k rpms. backfiring left and right. smokes a bit and smells like fuel. i started it on sunday it ran as described aboved turned it off. went out today, pulled the plugs, L1, T1, T2 were black, L2 was clean, compared to the others, but slightly wet. cleaned another set of used plugs turned the car on, ran as described above, pulled the, all are oily, trailings more so than the leadings, L1 more than L2.
any ideas before i pay someone to tell me i need a new engine?
thanks

Injector problem.
There was recent thread about it where the injectors were fresh from witchunter and he got instructions on how to tap on them to make sure they weren't sticking. It solved the problem for him, maybe it will help you.
Oh, and the wideband will help find a bad injector.

also make sure you have the jacobs wired in correctly and that you have the plug wires gong to the correct coils - I had the ign. harness backward so that the 2 trailing coils were swapped and it had similar symptoms
