I have a 1988 CRX HF with a b16 converted to obd1, the wiring harness is uncut. I got some new spark plugs went home and put them in then adjusted my TPS Sensor because it was out of spec' then started it up to go test drive it, and it immediately threw a code 3 "MAP". Ive changed the sensor multiple different time with know good sensors, ive changed the ecu multiple times still code 3. so last thing i ran 3 wire straight from the ECU to the MAP Sensor. and still i have a code 3, I cant get rid of it, Also i have no vacuum leaks and if i did it would be a code 5 any help!!
