Hey guys, first off, I have a 90 accord with a F22B DOHC Lude SI motor. just put a new F22B in the car because the last one was shot. Im having a few problems that i still havent solved and im getting desperate. here they are -
*Hesitation while holding at ~4-4500 RPM
*slowly became a problem big enough to keep the vehicle from starting
*changed out the dist. for my old working one
*car was able to run with TPS unplugged so i replaced it with a known good one
*NO CEL s
*When car was hesitating, the tach would fall out even though the motor was still around 3K


-- Im now down to very few ideas, like possibly the alternator, or ignition switch. Does this sound right? please someone help, i need to be able to drive this car soon. thanks everyone.

Tony
