Hey.

Bro I been going insane trying to find out an issue I'm going thru for the past 2months. I been looking at ALL of posted up threads.

° I recently changed my map sensor, that wasn't my issue.

I have an issue with my acceleration. It chokes between 2000-3000 RPM. Acceleration drops down as if it was to turn off. Then it will pick up on acceleration as if it was a delay. It acts up in & out of gears.

Pretty much my acceleration drop back down at 2000-3000 RPM & picks back up & backfires while passing 3000rpm. I can't explain, maybe I can text, email, or call to demonstrate the sounds.

I have done all my work on my car as far as putting the motor in & connecting all accessories. Car turns on & idles perfect & low just the way I like it.

I got a 92 Civic Si hatch.
• full stock 2004 PRB Type-S 6spd swap w/ harness.
• no harness cutting.

Issue is at Part throttle, not full throttle. Check with video, maybe you can make it out. I just had my boy record it real quick but he went all extra on the recording.


Check it out....
