I have a 97 plymouth voyager, 3.0 v6, 120k. It starts up fine and drive's o.k. but when I take my foot off of the gas pedal it stalls. As long as I am pushing on the pedal while in D it doesn't stall. When it stalls I need to put it in N and start it while given gas for it start back up. It is very cold here and when this problem first start I had almost no gas. Since then I have put gas in the van along with dry gas and fuel injector cleaner. Fixed a vacuum hose and cleaned out the egr valve. ANy ideas while be helpfull.
