What is causing this Check engine light
My check engine light is on and solid on my 2006 impala LT 3.9L V6. the
message center is telling me to tighten my gas cap... ive replaced gas cap 4
times now and got the car scanned for codes...got a P0455 so i replaced my
purge valve solenoid which is located on the top of the engine with no success
anything else that would cause this issue?
