Sometimes after awhile of driving i will get a code 3 (MAP) and my Vtec will stop working. When i reset the Ecu it is fine for a while but then does it again. it is an obd1 h22a in a crx. im also throwing a iacv code any ideas on how to fix that? i've tested the valve itself and its fine, so I guess its in the wiring. The connector at the valve has constant voltage in both wires while the ignition is on. If I wanted to wire it directly to the ecu what pinouts would I use?
