H22A MISFIRE & CHECK ENGINE

[nightrider93ex]

HEY GUYS WHATS THE DEAL...........I HAVE A QUESTION....MY CHECK ENGINE LIGHT TURNS ON WHEN IM ON A HIGH GEAR.....3RD THROUGH 5TH....BUT ONLY BETWEEN 2 1/2-3 RPM'S.....AND THEN WHEN I TURN THE CAR OFF THE LIGHT GOES AWAY UNTIL IM AT A HIGH GEAR BETWEEN THOSE RPM'S ONCE AGAIN.......IF I KEEP IT AT A HIGH RPM IT WONT TURN ON ........AND I DO HAVE A LITTLE MISFIRE BETWEEN THOSE RPM'S....I CHANGED THE SPARK PLUGS....BUT I DONT KNOW....ANYONE???

What code is it throwing?

I CANT CHECK IT....AS SOON AS I TURN THE CAR OFF AND BACK ON....THE CHECK ENGINE LIGHT GOES AWAY...

the code is still saved in the ecu's memory just read jump the connector and read the code.

how do you check it

I would almost bet that it is throwing a code 12 (EGR Lift sensor). That is exactly what my car did. When you did the swap, did you hook up all of the vacuum lines correctly? Did you bypass the EGR? Did you swap the wires on the ECU (A6 and A12 I think). All of those will cause a code 12 on an H22 swap. But yeah, it sounds like an EGR light.

WHAT DOES EGR STAND FOR....SORRY I DIDNT DO THE SWAP MY SELF....I GOT MY HANDS DIRTY BUT DIDNT DO THE WIRING

[4GAccordH22]

EGR=Exhaust Gas Recirculation

The EGR valve is between the throttle body and the dizzy (on the intake manifold). Should have a vacuum line from the box on the firewall to the EGR valve (I think the vacuum line is labelled 16) and a sensor plug on it. If either one of them are not connected properly, it will throw the code when the EGR tries to open. If the vacuum line isn't connected, it won't open and the sensor will see that and throw the code. I would say take the car back where you had the swap done and have them look at it. As for the pin swap on the ECU, that only needs to be done to the 5th gen accords. Basically what it does on the 4th gen is it swaps the EGR lift voltage and the O2 heater, so the EGR is always getting lift voltage and it will run like shiat... If you do a search, you'll find a post on how to run the vacuum lines, so make sure that they are correct. Or, like I said earlier, take it back where you had the swap done and have them fix it.

thank you my cb7 dudes

[nightrider93ex]

yo man i found that vaccum line labeled 16.........and its connected to a gold part right under the intake...i believe its a sensor.....and from there its connected to nothing......???? what the hell is it supposed to be connected to???

[xlr857]

Did you check your code yet. My car did the same damn thing. I was throwing codes 42 & 43. Knock Sensor / Vtec Oil Pressure switch. They were wired backwards because there in the exact opposite locations from the F22 and H22 blocks. We just assumed it was the same and I pulled my hair for 2 weeks fucking with that stupid knock sensor. If those are the codes youre throwing that may be the problem.

It's supposed to go into the box on the firewall and through a coupla things in there... I think the EGR control solenoid and sumpin else... I might be able to get close up pics of mine if you need em, and I have an extra "EGR box" that goes on the firewall I can open up and take pix of. Lemmeno

If You Can Man That Would Be The Shhiizznate(master Shake) Lol

This is what the EGR valve looks like...

Here are the innards (guts) of the box on the firewall...

line 16 is on the lower left ^^^

This is the EGR valve hiding on the intake mani vvv
...
The vacuum line connected to the EGR valve should be #16 and the other end of 16 should be going here ^^^

The line on my car goes under the CAI and snakes under the external coil to the firewall box. If you have a JDM H22A, you may not have the external coil in the way.

If you need more help than this, you're gonna have to bring the car to me so I can actually SHOW you where everything is.

BTW, who did your swap? I know you said you "helped", but you never commented on taking it back to them to have it looked at...
