i had my integra swapped with a b16a out of a 92-95 del sol 170 hp version and converted my teg to obd1. my vtec use to kick in but now it doesnt...... but also the check engine light has always stayed on im running a pr3 obd1 ecu the only sensor im missing is a knock sensor and the ecu is not even throwing that code.... its throwing eod, iat, and o2 sensor it was throwing vss but got that fixed still no vtec kick and the im just trying to figure out what i need to do because im ready to give up on this car it has had these problems since the day i brought it back from the shop. oh and the coolant fan works but wont kick on by itself plus when i did rig it up to work the car still over heats i changed the thermostat as well and found some gunk didnt know what to make of it though. please somebody help me

 

The vss will make vtec to turn on, have you reset your ecu since you fixed the problem? Does your sepdo work? Is your oil full and in good condition?
