Default A bad Miss at WOT in 3rd...

Hey guys, wondering if maybe someone here could help diagnose the problem here. We just got the motor back together a couple weeks ago after it broke a timing chain and bent some valves. Now its never done this before and nothing changed on the car besides the timing chain and valves. While going WOT and I hit 3rd gear the car picks up a real bad miss at around 4krpm. It doesn't do it at WOT in 1st or 2nd, just 3rd and higher. I just changed the plugs tonight to NGK TR6's and its still doing it. The old plugs I took out look great. I'm running LTCC and SVO 30lb injectors. Anyone have a clue?

What are your LTCC LEDs reading? Solid green with a blinking 3 red LEDs by chance? (same thing I had if so) "too many high res pulses". Bottom line was Bob Bailey emailed me back asking what my spark plug gap was and that he couldn't respond till the 17th. I ran out of patience with LTCC and went back with a new opti setup and new wires, runs fine now.

shoot me a pm with your # I'll tell you what all I checked on mine as far as diagnosing maybe we can figure yours out since you had LTCC running fine prior.
