Hello all NTTG Have a Ram1500 w/318 and the check engine light just came on. Checked the code, p0442. I'm going to pick up a new gas cap just for yucks tonight and start checking all the vaccum lines to and from the manifold and evaporator. Does any one have a schematic of where all the lines actually go in case it's not something really simple like the cap or a "t" or something.

Thanks,
Jay

 

pick up a chilton mannual for your truck. It will have the vacc and wiring diagrams for it. Not to mention info on fixing the other stuff

 

NO DOUBT! ^^^^^^
