There are a few procedures you can perform; 1. An accelerator pedal released position learning procedure 2. A throttle valve closed position learning procedure 3. An idle air volume learning procedure. I would start by checking to see if your electric throttle control actuator is binding up or sticking. Sometimes you can get a carbon build up in your throtte plate inside the throttle body which can cause the code you're getting and also check for a vacuum leak in the intake somewhere and also check the PCV system. These are the main cause for the code you're getting. If all looks good there and you need those procedures, feel free to email me directly at [email protected] and I'll be happy to make you up a PDF on how to do those procedures without any fancy diagnostic equipment but check the other things first to see if that clears up your problem. Hope this helps.....
SOURCE: slow acceleration, high rpm
This sounds normal to me! The engine will read that rpm when accerlerating lightly. It is the stall of the torque convertor. The oil pressure will always be higher when the rpm's are higher, or when the oil is thicker - cold.
Virbration? That is a different story. Oil won't cause that.

the dash voltage egulator probably went bad. First,check the battery & make sure you have 12 volts,not running. Check it again running & you should see about 14.5 volts. If that's good,I'd replace the guage assembly.
