Jeep is officially back from the shop. New clutch kit, rear main, and pinion seal complete. Ended up needing to replace the entire clutch, the old throwout bearing had begun to tear up the pressure plate.
Prior to dropping the Jeep off at the shop, I did replace the rear brakes; rotors, pads, and emergency brake pads. The emergency brake still needs to be adjusted a little but otherwise everything works fine. Discovered an interesting problem while changing the driver side rear brakes. The coil spring was not properly seated. With a little pry bar action and lots forearm strength to rotate the coil, I managed to get it seated properly and hopefully permanently. Could possibly explain the pulling issue mention earlier. Seems to drive mostly straight now or I'm simply experiencing placebo.
Plan to replace those sensors this weekend hoping I can start to diagnose the funky idle issue. If it's neither the TPS or MAP sensor, I'll starting digging into the injectors and see if the injectors, injector harness, or both need to be replaced.
Hope everyone is safe during this COVID-19 situation. I'm lucky enough to be considered "essential", so I am at least getting a healthy 40 hours a week. That being said, Houston is doing a horrible job of handling the whole situation.
