ok buddy obviously I'm asking cuz I don't know......you gotta start somewhere. I'm using a p28 ECU from a 94 Si.
Is the wiring harness from a civic non vtec the same as a wiring harness from a vtec civic excet for the one has 3 extra wirings for the vtec.
Because I my mechanic hooked up the vtec in pins A4 and D6 and then the car started throwinga o2 sensor and a map sensor code and the car totally idles wrong now when I drive it, when I let off the gass the car starts to bounce cuz its trying to keep idle, should this happen cuz the car ran fine b4 this mechanic claimed to hook vtec up.
