Hey all...I have a 90 honda crx si...with a b16a2 and a jdm p30 ecu.... the wiring is all screwed up...it starts...and runs....idle is a little choppy when engine is warm...it throws a code but i cant check it because i have no dlc

the harness is obd1 along with the ecu i think...
I am located in Howell/Freehold area and if theres someone who wants to take a look at it...I will pay to have it fixed!!...also any questions feel free to ask...

If you want to get your car straightened out, give me a call.

215-962-1423.

Are you sure it's OBD-1 and a P30?
Who did the wiring?

You can check codes on those cars, the check connector is located in the engine compartment on the driver side harness.

P30 is an OBD1 B16 ECU...OBD1 dosen't have the light you should still be able to use the jumper plug to check the CEL if you were closer I'd come look at it....
