I've got a 2001 Dodge Ram 5.2 318 automatic 4x4. About once a week, the truck will go into a spell where it has erratic throttle. In the video the truck is idling, and I very lightly tap the gas pedal just enough for it to even realize I pushed it, and the RPMS jump up to nearly 2,000. I also get a surging sound (similar to a vacuum leak) when I hit the gas. I highly doubt it's a vacuum leak though, since I only have the issue occasionally.
I've shown this to a few really good mechanics in the area and they have no answers. It doesn't just do it when the truck is cold. It will do it until it's shut off (no matter the temp or run time). It's done over an an hour and a half trip before.
Codes on the truck right now:
P0031: Oxygen sensor (replaced a week ago)
P0037: Oxygen sensor (replaced a week ago)
P1899: Neutral Safety Switch
Any ideas as to what it could be?
