i have an h22 in my accord. when i first got it, i had alot of problems with the ecu and o2 sensor, but I got it all ironed out besides an occasional miss when i put a heavy load on the engine. i assumed it was a fuel blockage or something like that. i think i was right, because when i took the fuel injectors out i noticed that three out of the four injectors had a hard washer that seems to rest inside of the head, the other one didnt have it. There was also a softer rubber washer that seems to settle around the injector. my question is does eveyone have two washers for each fuel injector, or is there just one?

 

Fom the mainfold to the fuel rail is as follows:
Fuel Injector Insulator
Seal Ring
Injector
Cushion Ring
O-Ring
