WILL I NEED TO CHANGE MY COMPUTER IN MY CAR IF IT STARTS TO SHAKE

Can you grab the tire/wheel assembly and it has looseness while stationary or is it a shake that starts when speed increases?
If it starts to shake as speed increases,you may need a wheel balance.
If there is any looseness when you grab it while stationary,get a look under there SAFELY!! and replace any loose parts.

Clean the EGR valve and throttle body

check fuel pressure , pump and filter

You need to check the choke on the engine for cold starts it chokes off air to the fuel mix . if it is closed to much the engine will want to die and shake. When the car warms up the choke opens and the car gets air and runs fine although the choke could just be part open. It still will need adjusting.

Hope this helps

Well, short of hurting your feelings.

When you brake you hear a strange noise. The sounds brakes may make, should be something you are familair with.

When doing 45 mph plus, the car starts to shake. Now tell me, youv'e not experienced this many times in your life!

Turning left or right could be a worn steering rack,mostly because you never change power steering fluid,or upper strut bearings or any other suspension parts starting to wear. Or, it's just you noticing different sounds, than when it was new.

When you turn the wheel too far to either side,you hear the power steering pump squealing and telling you to stop. Another bad practice.

Now I would conclude, that you need to strip all four brakes off the vehicle and completely go through some sort of brake repair or service. I hope you already figured that.

usually a rough running engine has nothing to do with an oil change you way have an oil leak onto the spark plugs or you may have a defective pcv system

it sounds like its struggling to get enough air when it idles,,,, check the air-filter,try running the car for a few miles without the filter, and if it makes any difference, then thats your problem

First lets start with replacing the spark plugs and wires. also change the fuel filter

check the vacuum hose
