I've got a 94 mustang with a lq4, victor junior, holley 750, 234/238, patriot springs, and 1 7/8 dynatechs. Using the 6010 box. Ive tried the pills, and my own curve and the problem hasnt changed. It starts up just fine, but then stumbles and backfires through the carb and exhaust. I through a timing light lead over the plug wire to show when it was sparking, and a few of the cylinders seem to cut out completely when i hit the gas. I called msd and they dont know what it would be. I have changed cam and crank sensors, checked rockers, pushrods, timing gear alignment. Also made sure we had a good ground and constant 12v. Anybody have this problem or have any input, Im lost...

You didn't like the answers on LS1tech so you came over here? Since the suggestions have already been made and you're not making an effort, then what's the point of posting on every site known to man?

What effort was not made? And I'll post on every forum I'm a member of to try to find the answer, why wouldn't I? I posted that today and I'm at work, not sure where you are coming fromComment

I'll go over them again. We added extra grounds from the block, and heads to the frame. I even ran a direct ground from the stud the msd box ground is hooked to to the battery.
I pm'd youComment
