alright, i did a mpfi swap, my car is a 91 civic dx, put a b16a6 from a 91 crx si. started right up. idle perfectly but wont rev high. i have searched and tried almost everything. but i notice in a pic i found on the internet the a part i dont have in mine. heres the pic

thanks in advance

 

First you must mean D16a6, not B16.

The thing you circled is part of the emissions controll system (purge cut off valve or something related to it) it shouldnt have any effect on how your motor runs, the part on the left side of that assembly is the map sensor.

I'm gonna guess that your probably going into limp mode (which sets a rev limit of 3500 rpm) check you ecu for CEL codes.

I'm getting code 4 and 14. I'm trying to find the crank angle sensor, but i cant find it. where is it located ?

 

its in dizzy had same problem

 

get a distributor

 

just to make sure i got the wiring right, the c1 wire goes to the blue/green, and the c2 wire goes to the blue/yellow, and then the rest is all color matching ? and there 2 white ones, one bigger then the other one. correct ?

 

just put a different distributor i found in my garage, still doing the exact same thing.

 

When you do a multi point FI swap don't you have to swap 2 wires around that go to the tps sensor?

yup, did it, and rechecked it like 1 million times lol

 

Since the dizzy is mostly color matchig for the wires have you tried to swap the 2 white wires around to the others? to see if that makes a difference.

 

i heard that if i didn't match the 2 white wires correctly it wont start at all, but ill try it anyways

 

swap the wires and just turn the key to on position to see if the check light goes on .. I could be wrong.. are you using the pm6 ecu ?

 

nop tried switching it and it just wouldn't start anymore

 

Try reseting your ecu.. you know now that your wiring is correct.. it starts and runs.. pull your hazard fuse for 10sec.. check the cond. inside the cap, I usually scrape off build up on the little prong thingy's that are inside the cap and scratch the **** off the rotor.. check your plugs too. weird problem their bud..
If all fails.. start checking the resistance against the terminals in the dizzy.

 

still getting code 4 and 14 (N)

and what do you mean by checking the resistance against the terminals in the dizzy.

it has to be a wiring probleme for sure, i just dont know what do to check if i have a short somewhere

 

alright, a little update. code for is gone and its not on limp mode anymore fixed it from making my own wire going from the ecu to the crank angle sensor. the one code i have now is the code 14 (idle air control valve, where is this located and what should i test or do ?

 

it should be on bak of intake man i had same problem i swap 2 wires at the driverside main connector i had the wire from the idle air control was doin nething and had 1 wire goin to a blank spot in the connector swiched them and code 14 went away i still have code 4 how did u fix dat
