Idle problems
I recently bought my first Jeep. A 2000 Cherokee Sport. I took it in to have it inspected and get the oils changed and brakes done. Since then I had noticed that at idle it sits at around 600rpm but sometimes jumps to around 900rmp then back down. My first thought is my mechanic unplugged my O2 sensors, but they're plugged in and LOOK fine. The battery terminals do need cleaned, I've heard that could be a problem. Before I took it in I seafoamed the oil, and gas due to some cold temp piston slap. Anyone have any ideas? I have a video, but don't know how to upload it.
