i bought a 92 del sol weeks ago it has a 96 integra ls motor in it. the car doesnt run right it bogs in idle and when try to rev it, it wont rev over 3k sometime just dies. who ever did the swap use the OBD1 single cam vtec engine harness for the OBDII b18b engine will it be the problem? also the guy i bought the car from told me that the car has the OBDII interior harness cuz it has the obd connector for scanner on the passenger side. basically is a 92 delsol with a b18b running a OBDI single cam v engine harness, ObdII sub-harness, and a jumper harness with a OBDI P75 ecu.

do you have any CELs?

First thing to check with your symptoms is MAP ... multimeter it and if you have a source check good working one. It sounds 2 me like a typical MAP problem

but is it cool to run a obd1 engine harness with a obd2 sub harness

dpetro1

yes.

do you have any CELs?

so wait, they put an obd2 body harness from another vehicle into your obd1 delsol, then used an obd2-obd1 jumper harness to run an obd1 ecu? man that's over working it... personally i'd get an obd1 delsol body harness in there to eliminate the jumper harness/body harness from a newer car...

are you sure you have the plugs from each sensor (tps, map, iacv, evap, etc) plugged into the right places?? Many of the plugs have the same 2-pin design allowing them to be plugged into various sensors
