CEL: EVAP leak & system lean?
Hello everyone,
My 2009 Corvette is currently showing CEL codes P0171 and P0174 (Bank 1 and 2 too lean) and P0442 P0455 (Small leak). I replaced the gas cap with a brand new OEM cap and the CEL is still showing. Not sure what else could cause the problem, I have noticed the car seems to idle a little rough on start-up but smooths out when the car is warm, I'm guessing the throttle body needs to be cleaned? Could this possibly throw a code? Any input would be appreciated. |
Was just the gas cap. lol
