ok i have a 1993 honda del sol (and i just bought it a month ago so bear with me) it has a motor to a B16A and its a 5-spd. I dont know what trans. is in it but i know it had a cable clutch and was converted to a hydro. clutch. im pritty sure it was converted to ODB1. I dont know what ECU is in it so here are the numbers on it... ASH, 470-210068, 37820-p30-010. so here are my problems- when i let off the gas sometimes i smell gas, and if i accelarate semi hard it back-fires. also i need to know what the guy who owned it before me did to the wiring harnes. on the mass of wires going in to the ECU he cut 2 and hand wired them into part of the harnes under the hood. one is on the A plug 'i think' its orange with a blue stripe and the other is on the C or D plug and its orange with a white stripe. and my last issue is im hooking up a air to fuel ratio gauge and i need to know what wire on the ECU to tap in to.
