I have a 2001 Ram 1500 Off-Road Edition that has some issues. When I go to accelerate and get around 2500 to 3000 rpms, it starts jerking. Not sure what the cause is. Today, I applied the brake, put it in drive, revved it up with the brake still applied, and it jerked, then died when it got around 2500 to 3000 rpm. Did some research and seen a number of things people posted that could be wrong; plugs to rotor cap, O2 sensors, etc. I unplugged the O2 sensors and that's definitely not the issue and when I did, I noticed it didn't throw a check engine light. Any help or ideas would be greatly appreciated. I'm not sure if it's the transmission or what it is. It's the only vehicle I have and my way to work.
