Code 45 is rich 02.Jump the aldl,like you would do to get codes. Watch the ses light with car running,the light should blink.The less the light is on, the leaner the 02 is.The more the light is on the richer it is.It really should be on as much as it is off.This is only accurate if the 02 is hot.Rich 02 can be caused by,high fuel pressure,ign.misfire,bad MAF,TPS,or even a charcoal canister thats flooded(just disconnect it and see). good luck!
