I have a 91 integra with a jdm b18c swapped all stock with the p72 ecu stock. the car runs like a champ until it is fully warmed up or after driving for a while. then it will just feel like it doesn't want to move no matter what rpm i'm at and takes forever to pick up speed. i have the rywire obd0 to obd1 conversion harness and have no fault codes other than the code 20 eld. i have tried switching wires around on the 02 sensor to see if it was the culpret and it is still doing the exact same thing. i also just replaced the fuel filter. and it has a "new" complete distrubutor, wires, and plugs. but it did all sit for a little over a year before i got it running while i was in afghanistan. Any help or advice would be much appreciated and i'll try anything really. thanks again.
