replaced the cracked turbo housing and found a loose ground (by the starter on the bracket). Guess I failed to double check everything after the tranny install. Drove for almost an hour and no surging at all. now just a few pics. cracked housing and the replacement. NOT GOOD!
as bad as the crack is, I think it progressively got worse. I believe the ground was the initial cause of the stuttering and the crack amplified it. I remember hand tightening that ground but never did snug it up. It was LOOSE like 4 full turns loose.
That ground is only for the tranny. Mine is off completely too...well was. My studdering was the homemade ram air. After Will saw me it fixed it. I did have a slight idle jumpyness which the new neutral switch fixed. The jumpyness was minor and lasted a second or two and then leveled off. Rick I'm 100% the cracked housing was your culprit. That thing has pressure and leaks. Have a after MAF leak = RICH. ECU yanks fuel and so forth. Studder. That's what you get for tightening the ever living crap out of that with a tbolt clamp :keke: Glad you got it fixed.
