So today something new happened to me.
When I was on the highway, my truck started to jerk a tiny little bit in 4th gear. So i pulled over, turned off my engine, and started it again. This time, once I hit 40mph it did something really weird. It didn't want to accelerate, and it revved in two separate intervals. It's hard to describe. Turning overdrive off made it worse. At that point I let off the gas and just drove as slow as I could home. When I was slowing down to about 35mph, I noticed my rpm needle moving back and forth quite a bit within an area of 250 RPM. I have no clue what could cause this and I'm pretty nervous. Sparkplugs were just changed last weekend.
EDIT: I would like to point out that my front o2 sensor is temporarily not connected to the exhaust because I have a little more work to do on it. Would this be the cause of the problem? I know it's causing it to run lean.
