Ok so I have a 94 civic with a b16a2 in it with a p72 ecu but my vtec don't engage and the vehicle redlines at 5500rpm. It is also throwing an engine check light for a o2 sensor (but has been switched to new o2 sensor) but still same o2 code throwing. Only thing I wired was converting the obd2 distributor to obd1. Let me know if you guys have any suggestions. I'd really appreciate it.
