My 2004 ZO6 is having an issue. I can go out for a long drive with no issues. But immediately after washing I get a check engine light and DIC error codes. PO101, PO102 & PO103. These various errors go away once the car has dried off which can take an hour or more. All four udders are now clean and installed correctly. There wasn't any wet gunk found anywhere, just very dry leaves.
No I did not wash the engine nor use a pressure waaher.
Is there a weather pack connector I should check and if so which one? I have no idea where any of these connectors are. I'm not too limber any more but willing to crawl under the car. Right now I have it up on my lift.
I am definitely not the best shade tree mechanic but with some help I hope to solve this.
No battery leaks.
Thanks.

Not sure how the MAF could have gotten wet, it's not showing any corrosion. I looked at it and cleaned it with MAF cleaner but if it's getting wet how would I stop it from getting wet. Thanks.
