so i have a 93 hatch with jdm h22a obd1 motor and im having some issues. I have already searched but cant find my problem.

The problem is while i take off the car starts to hesitate between 2500rpm and up and starts to backfire a little. Once i get into WOT it feels like its a whole new ball game and car starts to open up and around 6500rpm it starts to cut out as if im reaching rev limiter? A

*Im running a P0A F22 accord ecu and it runs "OK' (CEL on for code 41(o2 sensor)

*I have a chipped p28 with h22 program and it runs but worse than the f22 ecu(NO CEL)

*I ALSO have and tried a stock p13 and it runs a little crappy but once it hits 5000rpm vtec starts to kick in and then sort of bogs out

I have checked the timing belt and everything is lined up correctly. im not 100% sure but i think its still running on stock civic fuel pump?

Any help on this issue? I have been going crazy trying to figure this out someone help!

 

I'd like to know the answer to this one also.

 

bumppp

 

updates....i put in h23 fuel pump and map sensor runs alot better

One thing i noticed was cyl #1 spark plug wire that goes into the dizzy was releasing spark out from the wire everytime i put my hand next to it i would get a shockked lol i replaced the wire and ran good

i now was able to run my p13 and runs good and i feel all the power up top

one and a while here and there it hesistates a little but im just going to have to buy new spark plug and wires.

 

does it hessitate when its cold or just hot?

 

Is the Prelude and/or Accord ECU throwing a check engine light?

Code 12?

Just curious...

 

yes accord and prelude throw code 41 which is o2 sensor

 

both cold and hot but seems like when its hot it doesnt do it as much

 

So no code 12 huh? I assume that means you have the EGR system hooked up then?

 

when you pull the #1 spark plug cable out while the car is runnin what happens?

 

runs on 3 cylinders lol
it runs like it should starts sounding weird

 

You got shocked? man that's intense...

 

there is a thread on a strange power loss with the h22 check it out ... you might be having the same problem https://honda-tech.com/zerothread?id=2107210
hope this helps you out man... putting an h in my hatch right now hope i dont have the same problem...

 

I am having this exact same problem in a 2000 si. Keep me posted and ill do the same. I have tried a jdm p13 and a proven h22 program in my p28. Keep me posted and ill keep you posted. I have a jdm h22a.
