My girl has a 00 si and i put a CTR intake cam in and a GSR exhaust cam to and i drove it down the street and the light cam on its throwing the code (45) can anyone tell me what does cams have to do with rich to lean code???

 

did you reset the ecu?

first step to problem solving. if not then i don't know =P

 

Might be the cam is getting more air now, and with current fuel set up will result a lean condition.
Just athought.

 

i did reset the ecu and it still comes on i hate OBD2 ecus they suck i think i know what is wrong im going to check later today ill tell you if im right or not thanks for you help
