Ok I Am Getting Code 4 On My Ecu For My h22..sometimes when the car has sat for awhile the car will run fine and rev to its full max...but after the car runs for about 7 to 10min the motor wont rev pass 3 1/2...if any can help let me know...

 

Have you checked cam timing to make sure everything is at tdc? Could be an issue with the distributor. H22's are notorious for eating distributors, I'm on #12

 

dam..for real....i didnt know that...but i had my mechanic check it and he said it was fine....and i also had it checked by a shop
