Ive been having problems with my JDM H22 sputtering realy bad lately . I've come to the conclusion that the source of the problem is more than likely the injectors , as they for that engine model are prone to clogging . I'm looking into upgrading to RC or BOSH injectors but I need a little incite on what size's I should use . Im keeping a straight N/A build . Future plans [ Type S or Maule high comp pistons 11.1 or so= Head port and polish= head mill =Stage II BC cams = crome or hondata s200 etc . What size should I use now that will also work well with those mods. By the way my car runs great with load of pull whenever the cell code 43 pops on .

dude i had same problem and i got a 02 sensor from my friends 94 civic 4 door and it fixed the problem. after i bought one from ebay and i still had same problem i wanted to test one that i knew was good. so i tested it and bam it fixed my sputter problem. also remember to resest ecu.

 

yeah, i've had code 43 come on two different times, both times sputtering and running poorly afterward. O2 fixed problem both times.

once the 43 cel pops on, car goes into open loop, ignoring the o2 sensor, which is why it runs better. Mine did same

 

wow , you guys couldve just saved me a bunch of money, for now at least, and i've already spent so much on fuel and injector cleaners lol . Im gonna pick up an o2 asap. Btw what am I looking for, just a plain jane 02 for that model or something special? Which one did you replace, up or down stream ?

 

mine is OBDI so there is only one o2 sensor. I just used a cheap bosch sensor from the local auto parts store. They don't last as long as OEM Honda, but they are only $60 vs $200 for OEM Honda.

 

awesome that info is so helpful . I thought I had it all figured out with the injector theory, I thought the o2 code would've flipped if it were that but guess not. The help is very much appreciated .
