1997 Ram Van vacuum problem ???

[Bunky1267]

I have a 1997 Dodge Ram 3500 Maxi Van, 5.2 everything worked fine last fall then this spring we got it out to use it and I started it and ran it 2 minutes to move it in front of the garage to check it out, Then about an hour later I went to start the van it fired then spit back, I then restarted the van, Now the cruise doesn't seem to work and when I accelerate or climb a hill the heater or A/C goes from the vents to the floor. I don't see any vacuum lines broke or leaking, I did find a badly plugged air filter.


Anyone else had this problem??
