I had a swap from a 2000 b16 si into a 2000 ex and was running the ex ecu for 2weeks till i got thesi ecu. yesterday i finally had my si ecu i pluged in and drove it for a while. i parked the car for a while turned it back on and started to notice it was spudering when i hit the gas...it sounds like the block was drowning. it was also redlineing at 5000rpm. anyone think what it might be??? im hopeing its just a spark plug.
