Ok so i have a b16a in my 95 gsr, and i run a p28 chipped ecu. Now everything was fine, except for the CEL being on. My friend decided to cut the LS ecu harness where it goes into the ecu and rewire a gsr one... NOW MY CAR LITERALLY SPITS GAS OUT THE EXHAUST WHEN I TURN IT ON AND IT ACCELERATES BY ITSELF. NO CEL LIGHT IS ON ANYMORE. I believe it is the wiring. Can anyone PLEASE help me??

THANX
