I recently received a letter from Chrysler saying that my check valve in my 2005 Dodge Durango's fuel tank needed replaced so I took the vehicle to the dealer and had them replace it. Everytime I would fill up with fuel the fuel would come shooting back out. After they fixed the issue the vehicle ran fine for a day then the check engine light came and the vehicle stalled on the road. I took the vehicle to autozone and had them check the codes. Here are the codes that were given: P061C (electronic throttle control ETC level 2 RPM), P0300 (cylinder misfire detected-random cylinders), P0315 (crank sensor condition) , and p0340 (cam sensor condition). If they got something into my fuel system or if installed the part wrong would it cause these codes?

 

I would have a mechanic (not the dealer) look at it and I would assume the codes are not related to the gas tank purging fuel.

If you had to say what would you think it could be?

 

Maybe water getting into the coil packs because of the cowl being defective.
