Ok, so I got my rewelded intake back on...car makes plenty of boost now. I got into it some on the way home and managed to get about 25psi. The car starting missing pretty bad at part throttle and idle immediately after the pull. I pulled the plugs, they all looked fine, no oil, brownish color. No connectors loose, no codes....coolant level hasn't moved and the car don't get any hotter.
The messed up part is that more than 1/4 throttle and the car pulls smooth as ever with plenty of power....I can blow off the tires at 40. Under that it runs like it's intermittently on 3 cylinders.....surging and a terrible miss. Timing hasn't jumped....fuel pressure is rock solid and hasn't dipped....I'm lost. Probably going to hook a scanner up this weekend and drive it. Any ideas?
