I was driving down the road and the engine light came on

It started out running roughly and the RPM's were very high. Then it got harder and harder to start. Now it won't start at all.

Blew 15, 20, and 30 amp fuses

got a new window and the motor isnt' working.

Check engine light is still on, it was the catalytic converter but we changed it. now that?

sterring wheel keep shaking really bad.

There is a rattle when driving slow speeds and going over bumps. I wondered if it was from a loose exhaust piece

After I noticed the car over heated I fixed the problem and drove it right home. Tried to start it a few hours later & it won't start

AC blowing room temp air
Compressor hissing
Oil residue above wipers on windshield (was told to look for residue)
Check engine light came on yesterday (read out wasn't specific catalitic convertor was a possible cause nothing specific)
Noticed air same time
I am making a 1000 mile trip and had to turn around at 300 miles because my 3 yr old daughter can't have wind on her ears please help

First of all, I don't know this is common or not. I am a newbie.
I have 2 questions.
1. The RPM seems weird when 2 to 3 on D mode.
Here is the video to show you what's going on?

2. High Fuel consumption
My car is only 17 mpg in city. It's supposed to be 20 mpg.

Can someone help me with these 2 questions?

I got a nissan altima 2004, 2.5 L Automatic.
The engine shakes when I change gear from P to R or from N to D. Also the car jerks when changing gears from 1st to 2nd and a little bit from 2nd to 3rd.
Regarding changing gear from P to R, I have been told by a mechanic that the front right engine mount is broken and 2 other mounts are weak.
They had no idea regarding the jerks while driving and they suggested to show the car to a transmission shop.
By now, I dont want to pay more money for checking out the car by transmission shops.
Do you think the engine mounts are the only issue causing both jerks at idle and while driving and changing gears????
I am worried if I face transmission issues ...
Thanks a lot
