I did a B16 swap into my CRX with an OBD1 conversion harness. The problem is that after driving about half a tank the car has a random "hesitation" when you press the accelerator which eventually leads to a CEL #1. I replaced the O2 sensor with a boch universal, and when the light came back I again replaced it with an OEM Denso O2 sensor. Light is back, anyone got any ideas? its not immediate, and its a pain. could it have something to do with the gas cap? I have a wide body on it and I have a sparco cap, and I just filled up when this happened. I dont know, thing is starting to **** me off... Also, when I cycle the ignition the CEL goes away temporarily. any advice is appreciated. PM me if you can with ideas guys

 

Back up, this is the same exact issue im trying to diagnose on a friends car.
i some solutions fast.
