I got a 94 ls w/a 2000 gsr swap. The ecu i got for it is off a 93 gsr. I think their 1.7L's The ecu is chipped out so the vtec kicks in at 5500 and redlines at 9500. Problem is that sometimes i start the car and it keeps acting like it aint getting gas and bogs down to 200 and goes back to 1200 back and forth. Also my check engine light is still on any one can help me out?
