5g h22 swap problems...
DId the swap a few months ago, been slowly troubleshooting the problems/bugs with it.
Right now its running like ****, I cannot figure it out
The idle surges bad at like 1500, and it only surges from like 1400-6000 really fast.
The car falls on its face after like 30% throttle.
keeps throwing IAC code after a few minutes....
Replaced the thing, rewired the thing, all of it....
Is the any other pinouts that need to be swapped at the ECU besides the a6, a11 stuff?
The car is a 94 ex
Please throw me some ideas...
thanks

JDM motor?
year of your car?
is it in limp mode?
how's the gas mileage?
what's coming out the tailpipe?
etc...</TD></TR></TABLE>
JDM h22
JDM p13
94 ex
code 14
gas mileage is horrible
black smoke out of the tailpipe
the car is runing rich and falls on its face when you give it gas
I wired up an AFC in the car and I can go from full lean to full rich and the thing wont die. The AFC changes aren't working
He reset his computer today agian for the hell of it and it through the EGR code all of the sudden
I replaced the IAC, I rewired the IAC.
I got the yellow/black wire going to the power from the injector resistor, the red/black wire.
I got the black wire going to A9
I accidently touched the black wire to ground and it sparked? WTF
I thought the black wire was the ground/signal?

are you running your resistor pack and the right size/type injectors?
have you done a compression test?
how about a leakdown test?
are you running a stock honda OEM FPR?
have you measured your base fuel pressure? may be too high
is your O2 sensor working? may be torched by now
so if the AFC changes aren't working, then there is something fundamentally wrong with the wiring.
have you checked each wire from the distributor to the ECU? i had to just to make sure everything was good.
also, if you can find one, try swapping ECUs with a buddy to see if that works. sometimes they get banged up en route.
have you found what the code 14 is for?
are all of your vacuum lines hooked up the right way?
what about the IAV and the Fast Idle, have you checked those?
i recommend resetting your AFC until you can find out the issue, then tweaking it to adjust the curve you'd like.

Stock injectors, stock resistor pack, I did swap back to the Stock accord injectors and it ran worse
have you done a compression test?
No, didn't thinkt he compression would make it idle like crap?
how about a leakdown test?
Nope
are you running a stock honda OEM FPR?
Yes
have you measured your base fuel pressure? may be too high
No, stock fuel pressure reg.
is your O2 sensor working? may be torched by now
No code?
so if the AFC changes aren't working, then there is something fundamentally wrong with the wiring.
have you checked each wire from the distributor to the ECU? i had to just to make sure everything was good.
nope, haven't checked because I used the stock wiring for that and I am throwing a IAC code, not ignition or crank code
also, if you can find one, try swapping ECUs with a buddy to see if that works. sometimes they get banged up en route.
Tried putting in a stock eg CX computer, tired using a stock eg DX computer, tried using a 94 ex computer
have you found what the code 14 is for?
code 14 is IAC
are all of your vacuum lines hooked up the right way?
I took all the emissions **** off this car, no vacumm lines
what about the IAV and the Fast Idle, have you checked those?
the fast idle is bypassed at this point to narrow down problems
i recommend resetting your AFC until you can find out the issue, then tweaking it to adjust the curve you'd like.
The AFc wont adjust
