#333377 You need a pr4 ecu. Take a look at the ecu you have at the moment and make sure that it is one. You can also run a p75 with a 0db2 to Obd1 convertor harness.

#333395 p75's came obd1 as well. 94-95 integra rs/ls/gs/"se" whatever trim as long as it has a b18b1 in it.


if your car has the correct ecu pr4 or p75, doesnt matter, then id check calibration on TPS and test coil/ignitor (or if you have a buddy who has a good LS distributor just swap the distributors)

any check engine lights?

#333397 Ive replaced the coil and ingitor. I know its not the dizzy my friend thinks its the ecu

#333409 You should obviously swap it for one of the ones mentioned above. Should be a relatively easy find at a junkyard or even craigslist. :thumb:

#333423 doesnt matter what OBD your engine is, if its in a 92-95 Civic, then its being ran as OBD1, since they came OBD1.

Have you checked to see what ECU youre currently running? If not, do that. If youre on the wrong ECU it probably wont run well and could be the root of all the bogging, and whatever other problems youre having.
