alright well i have obd2 b16 putting it in to a 93 dx obd1.. im using the stock harness... i got the motor in and it starts up and runs but boggs sounds like it it cammed bad... well when i give it gas it will bogg... i checked the timing and it right and checked the spark and fuel injector... i have a plug that cames up kinda by the timing belt and was wondering if that would be the top dead center sensor... and its not plugged up and i dont have a plug for it on my stock harness... i have a plug that will go into it but i dont know where to wire it in to the stock harness.. and if you guy have any other ideas... also i tried to use the cel plug to check for codes but when i looked on the write up it said it was a grey plug with like black red and white wires... but the only plug i could find was green with a brown and blue wires in it so.. but let me know if you know what to do with the plug on the side of the block...
