first off my senior prom is this saturday... i put in a used pettit streetport/pettit ECU during winter, drove it out and it ran 8psi...thinking it was the ecu i swapped the pettit ecu with stock to see if i would get good boost...i got 12-13psi which was good...however it wasnt the ecu but a shorted/loose harness...it sat in the driveway for a couple weeks while i put a greddy intake and its worse now...it runs but when i get about 1 psi it boggs down and the CEL comes on...havent pulled the code yet but theres really no point...im sure the harness is the problem...i naver had any codes before i parked it...when i wiggle the harness at idle sometimes it pops and stalls, sometimes it idles way up,...i have a short/loose wire somewhere...what would you guys do??

all im looking for is advice...i really need to get it going by saturday for prom...i understand theres a few good people in my area that deal with ECU's and wiring...but with no experience with a rotary should i take it there??...i just want it done by saturday

what would you guys do???

thanx
