Why would a 1994 Dodge Caravan die when it gets warmed up?
Check the cam sensor and the wiring harness that runs to the cam sensor to make sure it isn;t pinched or crimped, especially if someone has recently worked on the vehicle in that area, if the wiring harness is not put back where it was it can get extremely hot and short out causing the camsensor to malfunction, when it cools off , it will work fine. I had this problem among others with a 93 grand voyager.
I detail used cars at local dealerships and I have restored many Caravan headlight lenses. I use a product called Crystalenz, it works great and is really easy to use. You DO NOT have to replace the lenses. Check out their website www.crystalenz.com for more info. for removal, see: How do you replace the headlight assembly located on a 1994 Dodge Caravan?
