Have dodge caravan se with 83.000 miles on it engine light is on with a code po455 po442 and car stalls while driving but will restart again, thats the only code that comes up.


Hi:
These codes are part of your evaporative emissions system, and can be a real challenge to troubleshoot and repair. Most people start with a new gas cap, but end up checking hoses, charcoal canister, and evap control solenoid before all is well.

I know this isn't the answer you were looking for, but at least some direction!

Evap Emissions Leak


This can be because the Gas cap is not holding the pressure. I would start there first.

Code PO442 & PO455 on a 2003 Dodge Caravan with 3.3 engine


The problem is most likely to be with your vacuum line they put cheap rubber hose for this purpose. You should find a diagram at the front of the vehicle trace the hoses by this diagram. You most likely will find a bad piece of hose.
