With a high engine idle and loss of power it suggests a vacuum leak allowing the air fuel ratio to be too lean. As for the brakes burning that suggests that the brake booster is faulty and that may be where the vacuum leak is.

thes is bad , start with looking under the gas tank all the way to the engine as it code be leaking from any where my frinde mostlly u can see it if you just check it

check all the wires under the hood. There may be a burnt wire that powers all the things you mentioned

it sounds like the motor may have burnt out

Since power outages aren't always polite and absolute, your fridge may have been subjected to low line voltages for an extended time and gee, Whirlpool still hasn't figured out how to protect their product from this kind of damage. We lost one the same way years ago in CA; we came home after being gone for hours, smelled the fridge, checked the line voltage which was wandering around 25 volts +- ~2 volts. Enough to burn the compressor windings but not enough to start it.
In that case, the electric company paid for the compressor replacement on our two-year-old Whirlpool. If you can dig up anyone who was noting the line voltage, maybe you can file a claim with your utility.  

Is the brush roll turning while on the carpet. If the belt is old, then it has stretched and will slip causing a rubber smell. But if it is an electrical smell, then your motor is failing and will need to be replaced.
