Can anyone help me with the following:

1) My malfunction light came on "Check Filler Cap" along with Service Engine Soon code P0442 (small emission leak)...I replaced the filler cap and that resolved the "Check Filler Cap" light.

2) Next the Service Engine Soon light came on with the previous code P0442 and I replaced the fuel tank vent valve...located in engine bay.

3) Now the Service Engine Soon light comes on with a different code P0456 (small leak-emission)

I would appreciate any help as i'm going nuts!

Thank, Ron

 

fwiw ; if it isn't effecting the performance i'd ride it out as it may solve itself. but if you think you may put us into the next ice age then p.m. the doc. he'll probly know .
