reposted....hey wats up peoples.... i just installed a skunk 2 IM and a P73 (USDM type-r) ECU on my 01 GSR and now im getting a CEL code 45 "too rich or too lean".... i hooked it up on the OBD2 scanner to get details and it said that im running rich... the only engine mods that i have are a skunk 2 IM, injen CAI, and the P73 ECU... has anybody else encountered this problem with the IM or the P73 ECU on a GSR?

 

Did you install an adjustable fuel pressure regulator and gauge when you did the swap? I think it's recommended to do so. If not, go ahead and do so.

 

you know wat...... haha...i was thinking of doing that to solve the problem and lean it out...but i didnt want to do that if there is a possibility that something else is wrong with it... git might come down to that .... by the way...GO RAIDERS! haha
