Hi, I'm havig problems with my van. It starts fine and stays on but it rev's up and down quite a bit and when I try to give it gas to go, it dies. It's as if I wasn't even pressing the gas pedal, just backfire then die. I added a container of "Heet Gas9Line Antifreeze & Water Remover" and it does pretty much the same, starts up like a champ but the idling goes up and down, sits for a while then starts to die down but the idling picks up and sounds like its going hyper, then dies down again. I can let it idle fine after it warms up, but takes a few starts to get warm. These problems have just started happening in the cold weather, ran fine before. Any help would be appreciated, thanks in advance.


This has happened before also but after warming up and driving for a while it ran just fine, had a minor backfire/not accepting gas issue once before but this time seems worse.
