I bought a 1993 civic with an H22 swap and it stumbles when the tap the gas, and has no throttle response. It is so slow. All the wiring looks pretty ghetto and I dont know exactly what needed to be wired for the swap. Any suggestions on where to start looking for a problem? The only code it shows is VSS while driving, and it has new spark plugs and a new ICM. Thanks

i dont know why but i have the same problems too, but only when im in fifth gear cruising, but when im getting on it its fine. somebody told me it has something to do with the ECU. but i dont know what ecu to use

 

Check your plug gaps, and timing.
