i know this has been talked about a couple of times b4, i have a fresh built h22a1 in a eg hatch and when i dropped it in i have code 43, i have changed out the o2 with a new denso, new set of injectors that i knew worked good and i have about 38 psi of fuel to the rail does any one else have any other ideas any help would be great

 

could be injectors, fuel filter, gas cap, fpr

 

Have you followed the troubleshooting steps for this code, which are outlined in the service manual?

 

i replaced all of the fuel filters even the ones inside of the injector just for what ever i guess, i havent replaced the fuel cap didnt think that would cause a problem since the system does become pressured, changed out the dizzy with all new parts and put it onto another car to make sure it was good, and im useing a h23a1 for a fpr cuz thats all i had is their a difference ? and i went by honda yesterday and got the info on how to check code 43 so i will check that out tonight

 

should of replaced the fuel cap. that takes probably the most abuse of tightening and closing. besides throwing a code if it was not tight enough for 3 trips of stop and starting.
