Just got my hatch running with a 2000 ls swap. Using obd2 harness and sensors, etc. Just plug and play, and using a obd1 p75.
The car is running extremely rough, wont accelerate, no power etc. Timing is good, fuel is good, spark is good.

Took the vc off and the cams are right on, dizzy is on...new cap, rotor, plugs..... plug wires are good...dont know where else to look??

Are all obd2 injectors the same... cause i'm using one ls injector and 3 hx injectors, i hope this issnt my problem :X

hey man, i had the same problem with my swap... i swaped out my D16Y7 for a 96 LS motor... we used the Y7 injectors... and to my surprise the motor would run like crap... changed out the injectors and solved the problem... if you took the injectors from a Y7 they are 190cc/min and all other D and B series motors use 240c/min. the Y7 is the only motor that used the smaller injectors

 

hx = y7 ??

 

I guess my o2 is my problem: https://honda-tech.com/zero...age=1

 

was better for about 10 minutes now its back to the same ****

 

She is still running really rough at idle and while its cold. Once it is warmed up it revs through the powerband better and smoother, still is pretty choppy at idle though.

I'm dont have either torque mount in yet, so i dont know if that could be related?

 

 

I'd put all the same injectors in first. That could be your prob for sure.

 

could your map and tps just be switched and its not throwing a code for some reason? or maybe your iacv and iat? those are all the same plugs and kinda in the same area. just a thot i doubt thats its but anything is worth a shot

 

all the plugs are good

 

FINALLY SHE THREW A CODE TONIGHT, 43 - fuel system failure??


Such a generic code .... any suggestions?

 

much like several have said....have you changed the fuel injectors?

 

yes just put in a known workign set

 

ok....

when you took the valve cover off, did you see a lot of crap in there? Like dirty ****? If so....try some "BG" after an oil change.

 

nah, motor is clean as a whistle. Out of a 2000 ls, with like 42k on it

 

sounds like aproblem with the dizzy

 

Have you checked your fuel filter to make sure it wasn't clogged.

Fuel pressure looks good, and the car ran fine when it was stock

reset the ecu and the code came back...so it wasnt a random one like most people get. Runs smoothe once the car is up to temp, so that sort of rules out a faulty o2 ...
