well i put this motor in my s14 a couple of weeks ago and for some reason i cant just floor it. Or it falls on its face and starts misfiring i have to ease into the gas to make it pick up speed. i changed the plugs and gapped them and i changed out the wires with other ones i also changed my fuel pump again and the filter. im thinkin its the throttle position sensor...because i unplugged the maf and the car tryed to die so thats working but when i unplugged the tps it still runs the same just asking for second opinions if it could be anything else

check the voltage at the TPS.

i'd also check spark timing with a timing light. both at idle and to try and see what it does when you rev it.

it is usually a fuel problem.

compression issues can also cause this kind of issue.

Start w/ tps. I had the same problem once upon a time and that's what it was.
