Hello my fellow accord owners, I'm new to this forum, well new to registering. But i've been having a problem with my 94 Honda Accord Ex. I recently replaced the head on my f22b1 engine with another low mileage one due to a timing belt jumping. I followed everything in the service repair manual for things such as timing and putting everything back together. Fast foward all the way to now the car is mobile. But I have been having an issue with the car not being able to go past 3k rpms, it misfires then goes below 3k. I just replaced my ecu from my friends running 94 honda accord (with no electrical issues) and the problem is still there. What really trips me out is that there isnt any check engine light codes coming on, even when I jump the 2pin connector under the glovebox. What else could it be? Ive looked on every single forum and havent got a solid answer yet.
