You left out a lot of needed information but I will try to help out.
You can pull the spark plug wires off one by one while the engine is running to see if you have one or more cylinders are not firing. Depending on how long it has been I would do a tune-up first, replace spark plugs and wires, filters, fluids etc.
With that done and if all cylinders are firing pull the transmission dip stick and look at the fluid, I am assuming you have an automatic tranny. The fluid should be a light red, if it is brownish and has a burnt smell then you could have a problem with the clutches inside your transmission which can cause this same problem.
Good Luck.

Great question. Well written. Easy to understand, (unlike many others we get) This is a pretty well laid out problem for a specific fixya expert with expertise on that model car. That may require a detailed answer. But you have come in as Anonymous person. I thing you would get a better response if you had a real name.
From my experience, I know I prefer to leave anonymous people unanswered.
Good Luck

Truck vibrate in park

Motor mounts, inspect, remove, replace. Might want to check transmission mounts, usually when 1 goes, the others aren't far behind.

04 acura ti 3.2 litre engine vibration from idle to 1500 rpm

Wow thats a bunch of miles for only 9 yrs.
I would want to know if it is something related to the engine or transmission, or the wheels and suspension.
Does it happen in all gears, and at any road speed ? Can you rev up the engine and make the vibration, or does the car have to be moving ?

Steering wheel vibrating really bad all the sudden

you have an issue with a front tire more than likely. or could be the front rotor. I would bet my last breath its' tire or break/rotor related. Maybe even a wheel bearing but it usually doesn't cause vibration in steering wheel.

1996 Dodge Ram 1500 vibration while driving only felt from drivers seat

No the idle issue is not the TPS, it is a sludged up throttle valve and automatic idle speed control air bypass valve. The procedure below should cure the idle issue. As far as the vibration goes this needs a hands on diagnosis by a good noise and harness trained tech, tire shops are good for this technican as well of course the Dodge dealer. Find below the cleaning procedure for the throttle valve and idle valve
Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional

Can a motor mount going bad have anything to do with rough shifting?

Vibration in the steering wheel on a 4wd truck

I just had the same issue with a 1999 2500HD and the vibration got worse above 50 mph. Problem was resolved with a new driveshaft. Old one (aluminum) was badly out of true and the problem didn't really occur until I had the U joints changed - then bent driveshaft vibration was noticeable. New driveshaft resolved issue.

1988 GMC 6ci truck vibrates at idle or when i stop at stop signs

Find your EGR valve & try disconnecting the vacuum & or wires to it temporarily and see if it changes anything. Be sure if it has a vacuum line, you plug the line with something when you remove it.
