RPM needle is acting funny and my car sounds like it wants to stall?
When I start my van the RPM needle is moving up and down by itself.
It is also doing this when I drive.
when I give it gas or when driving it sounds like it wants to stall. Also when I am driving the van feels like it is jerking, when it jerks, that is when it feels like it wants to stall.
The van is a 2000 pontiac montana.
Any help would be greatly appriciated.
