Your throttle position sensor should be located on the throttle body opposite of where the throttle cable hooks on too. Look for a small black box on the other side with wires leading into a connector. get your codes read and re post them it could be a simple fix.

Just because you cant feel in doesn't mean it isn't slipping. The computer monitors input rotation speed and output rotation speed of the transmission. If the output isn't within a certain range the computer stores this code. The only reason for this is transmission slipping and will require a rebuild.

The electronic door actuator on the drivers side has gone bad. It's common on the gm's and dodge since there very similar in parts and think that come from the same supplier. There is a electric motor with worm gears that crack and the door no longer moves to open or close to adjust for the temperature coming out of the vents. You have two of them, one on the passenger side and the other. You guest it on the drivers side which i believe is the harder one to get to. You may be lucky and it may be just a wire harness that may have gone loose, but i doubt that. Best thing to do is go to Auto Zone and have them check for a DTC code and if there is nothing. asked them for a step by step instruction to replacing the part you need and have them price it. It will be cheaper then the dealer or if you like after you get the instructions. You can go to the salvage yard and find one still in a car like yours so you know how hard it's going to be to replace it and the price will be average if you remove is like $25.00 with a 90 warranty. Good luck and keep me posted.
I'd suspect a sticking injector--car should have set the check engine light. Read the code(s) to progress further. If the coil pack were a problem, it would not be likely to fix itself. If the codes indicate an injector problem, try an injector cleaner in the fuel--worst case, replace the bad injector. The codes should indicate which cylinder to change the injector.
