H22B/H22B1 problems - HondaClub.com

Hoppi18 · 05-25-2008, 03:43 PM

I just had to swap out the engine in my wifes 94 Honda accord (EX I think). I didn't notice till I had everything swapped and the engine was running funny that the original engine was an H22B1 and the new one was an H22B. This is the first time for me to do anything this extensive on a Honda and so far the only diffrence I can find is that the H22B has no spot on the head for the EVAP sensor stuff. Right now the car will idle fine but when I push on the throttle it will bounce up and down between where it's suppose to go and idol. it doesn't want to stall or bog. a friend said that the EVAP can control preasure in the intake for smoother running. if that's so is there an alternate spot on the engine where the EVAP Purge Control Solenoid can plug into or do I need to drill a hole in the head? Or can I just get the CPU reprogramed? In Desperate Need Of Knowledge

Get the ECU that matches your engine. And make sure none of the other fittings are in the wrong places. There probably is a way to tap the EVAP into the head, but just swapping computers is much easier (as long as the rest of the wiring is the same and I don't know the answer to that one).

By the way the motor is a F22b1 if its Vtec. And if its Non-Vtec then its a F22b2 that way you don't buy an ecu for another motor. The H22 is out of a Prelude..Unless you have the Euro Accord Type-R .
