ok i went to the junkyard and found a 90 civic ex i know that the 90 civic si and ex are simlier so i buy the intakemanifold and the ecu. i did all the wiring right for the injectors and restor box but i used my distubriter now i can't go over 20 mph on first gear and idle jump and when driving and when i hit it full throttle the bogs out and starts shacking. and there is a round sensor that has two wires coming out of it the wires are black/yellow & blue i don't know where they go. so can anyone help me plz thank you.

 

I don't know where to begin, so let me start with this. You CAN'T USE YOUR DISTRIBUTOR WITH MPFI. It won't send the correct signals to the ECU and therefor will put you in LIMP mode if it even runs at all. Please take a picture of the sensor in question.

 

it is on the right side of the manifold onthe back away from the throttle body
