okay, so i think my motor is doing great. it has the hesitation problem now. i hate it! now i hear a knocking sound, but its still getting 25 mpg city.....spark plugs maybe? ive had iridiums in there for about 9 months now (~21k miles) and have used and abused them at the strip. the cap and rotor have about 40k miles on them. any ideas? it just gets annoying when i press on the gas and it just kinda sits there.

when the motor was swapped, all was replaced:

major seals
head gasket
water pump
timing belt
plugs
fuel filter
dist. cap and rotor
plugs and wires

the hesitation is more like, if i press the gas, either its slow accelerating or just pauses for a second or two usually below 2500 rpm. (gets annoying when you're trying to turn left on a busy road) the knocking is almost like a LOUD valve tap that i just noticed last night coming from the passenger side of the motor it sounds like. i don't really know how to describe it in great detail, sorry. but the hestitation, as i call it, is just like it sits there before it decides to go and then is kinda jerky when it decides to go.

i have the timing on whatever the honda place set it at. havent touched a thing other than normal tune up, etc. i run on 89 gas

that's your problem buddy. you gotta put 93 or higher in the F22b. if not your car will run like SHlT. try that out and let me know how your car runs

^^^ well that might the case if he recently switch gas types.

but do the bascis first. check wires, cap, rotor, plugs, and ignition timing. let us know how you fixed it.

do you find that it is hard to start up?

you might also want to check fuel filter to make sure its not that.
I seems like your not getting enough fuel. how many miles are on the car itself? you may need to look into a fuel pump or something
