I have a H22A swapped in my Accord. Also did a tranny swap... Dont think that should matter... Car is OBD II. ecu and engine is OBD I.... Car is throwing codes ... Got a check engine light that is throwing an O2 code but the mechanic says its fine. I also have an EGR code. He changed it and it still had the same problem. The car is running rich when the car is cold in addition to that the car has major hesitation when the car is cold. Once it warms up it is fine. He is kinda stumpped on what is wrong... any help would be appreciated. Only 1 of my 02 sensor is plugged in so it is not that. Pretty sure the wiring is correct... bc we used a piggy back had the same problem then he wired it by hand it still had the same problem.
