Look to replace the TCM throttle control module

The vibration is a sparkplug that is misfiring. I would start by replacing the spark plugs. Also just in case add a can of dry gas to eliminate any possible water problems.

Look in the interior fuse block. It is located on the drivers side of the center counsel, just to the right or where our right leg would be. You will need to remove the trim panel. The fuses will be labeled on the inside of the panel.

Does it have a picture of an engine does it say ABS, SRS VCS

The two boxes are located (one; engine management and lighting circuits) under the hood by the battery and (two; in-cabin accessory and lighting) under the dash by the driver's legs.

Hope this helps,

battery is weak.

One is front of the cat, and one after the cat of the exhaust.
The OBD Scanner should tell you which bank is producing the error.
Bank one is the front one.
