h22a Problems
 

i recently swapped a jdm h22 red top into my 92 prelude. i am having drivablilitly problems now. I am running a obd1 p13 ecu, no check engine lights. Idles good, but intermittently as i am driving the motor seems to have a sudden loss of power. Kinda like a fuel cut or something, motor is still running but when it does this the motor doesnt seem to accelerate at all, rpms fall, then suddenly power just pops back in. sometimes it will sputter first then does as stated above. When you press then gas while it is doing this you can hear the intake pulling in air but RPMS still fall at wide open throttle, but this is a consistent problem the whole time i am driving. The EGR system checks out, but when i unplug the EGR valve, the CEL comes on but the problem goes away, again though i have checked out the Valve, Solenoid, and Vacuum diaphragm and they all come back green, Vacuum lines also all appear to be in the right place.

I checked:
EGR, EGR Solenoid,
Switched the computers with my h23 computer (same issue)
Traced the wires to make sure the EGR solenoid was getting power
and resistor box is within honda specs
changed the cap, coil, plugs and wires
Checked all vacuum routing

anyone else had this same problem with a JDM h22a swap?

I believe the "red tops" were OBD2

thats my mistake, its just a h22a blacktop. Didnt quite have the money or time to try and put a redtop in.

What distributor, I would check the timing
