I went to the car wash about a week ago. I heard a noise but did not think to much of it as the washer made its way around the back of the car. It sounded as if it had caught my license plate and, "jarred," it.

Upon my next fuel up the car would not start and threw a CEL.

Codes were as follows:
p0496
p0420
p2237
p2188
p0442

Now I hear a weird , "whoosing," noise near the gas cap area and there is vibration back there every 10 seconds or so. Any one have an ideas?

Thank you.

 

You might get more replies if you provide the OBD2 code descriptions along with the codes (so we don't have to look them up).
