Alright, well i got 93 prelude h22a swapped, so i took the motor out and resealed, new head gasket, new timing belt stage 2 clutch and light weight flywheel. alright when 1/8 throttle at about 40 mph and 3k rpms, it will start bucking really hard, almost like a misfire but at the same time feels like cutting out. so i replaced plugs, wires, and new distributor cap and rotor, knock sensor. I NEED SOME HELP !!!!

Are you getting a cel, if you are pull the code/s.
Could possibly be main relay, it might be dying.

 

Sounds like the infamous 3k hesitation problems that the ludes are plagued with. I have it as well but only when the car is fully warmed up. I dont even know where to start looking to be honest.

 

Sounds like it could be in limp mode. Check for codes. Make sure you used a "shielded" wire for your knock sensor wiring. I'm not sure if this car had the h22a1 wiring already in it or not. Just going on what you've said.

 

well that could be an issue we did have to fix some damaged wires, i think i did replaced the knock sesors wire with a regular wire, maybe ill try the shielded wire would fix it. no codes though.....
