Ok well I installed an ITR intake manifold w/ fuel rail and injectors about 3 days ago and have had no problems, runs great. But today, I was driving and noticed my check engine light was on and pulled over and checked what the code was, it was a code 45 (running too rich or lean) and I pretty much figure it's running rich because of the ITR injectors. My question is, will this lead to problems and should I just put the stock b16 injectors in? Thanks

ITR injectors are the same size as 00 si injectors... both are 240cc. how's the idle, is it jumpy or is it steady?

Si Punk

Hmm ok well the idle is fine, except for when I just tap the gas. When I just tap it and let it go to like 1.5-2k it comes back down and bogs down almost till it stalls it feels like and then goes back up to like 700 or so.

Unplug your ECU (or pull the ECU fuse) for about half an hour to reset the ECU so it's XRAM is erased, then see how it goes. The ECU needs to relearn with your new bolt-ons..

Bert

i would try this too. i can't think of anything else wrong.

Si Punk

ok just did that, unfortunetly after installing the old stock fuel rail and injectors pain in my ass...but yeah we'll see what happans in a half an hour

btw is there any difference between the 00 si and the ITR fuel rails?

Thanks

Bert

no difference, all b series 92+ are same.

Si Punk

Ok, straight, thanks a lot. I just plugged the ECU back in and the check engine light went off ran it for about 10 minutes and nothing. So, I think all is well. Thank you guys

update

Check Engine Light came back on, I reset the ECU just in case, but I have a feeling my car is running lean. It seems to kinda hesitate when I push on the gas and if I'm at higher RPMs it doesn't feel like it's going as fast as it should. Not sure what to do, any advice would be greatly appreciated, thanks.
