Ok, so the DA has an OBD2 ITR swap in it and the car runs pretty good. but for some reason at 1500 rpm's(if held there) it jumps up and down, similar to 2 step. i changed out the map sensor thinking it might be that but no luck. any body please chime in! not sure what the problem would be.

 

anybody?!!

 

any codes? my civic with b20 swap does that occasionally too. i've checked everything in the ignition system, IACV,TPS, two different throttle bodies...no codes or anything...hmm..

 

it's your distributor wiring. make sure they are correct from obd0 to obd2. that happened to me before.

 

it doesnt have any codes. good call on the distributor ill check that and get back at you.
