resencly i bought a VAFC 1, after hooking it up to the ecu. it kept giving check engine light. (code 3)map sensor and i got a new map sensor. i thought it was a VAFC shortage, so i got another one. but today after i pluged it in. it gave me the check engine light again, and i checked every wire on the ecu and it was all fine. I WAS WONDER if anyone can help me finding a diagram for OBD0 vafc user manual.
