You change One spark plug, and One wire at a time. Do you know where your timing belt is? If not, its on either the right or left side of the engine. There is a covor to the timing belt. You take the First plug that is closest to that belt. Then you work your way to the next closest all the way to the last one. Remember, you have to do ONE at a time.

Try cleaning the IAC idle control valve. Buy a can of brake cleaner or carburater cleaner and with the car running at 1200 rpms spray right into the fuel system area where you take off the duct work for the air cleaner.The idle control valve can be removed also and the 2 holes on the under side of the valve cleaned. They get dirty and cause rough idling or no idling.
If not, have your car scanned for a code to check if it is the IPS (idle position sensor.)
For the gas filling problem , do not stick the whole nozzle in. Just enough to where you can pour the gas without the nozzle clicking off.

My Son's 01 Sonata displayed the exact same systems and it was his catalytic converter. The metallic sounds were the converter guts disintegrating.

Higher octane gas 93 with some good octane boost in the black can at autozone cost about 7 dollars or a bottle of 104 octane boost. Change the fuel filter. Probably only one coil pack is bad. The OBDII reader should tell you which one was a misfire.

right renew the glow plug timer/relay if you put a meter on the glow plugs when cold and turn ign on (with help) it should supply power for a about 20 secs ,time depends on outside air temperature ,if all else fails then do a colin --- use a push button switch,wired to a relay so glow plugs can be operated by pushing the switch which you will mount on the dash ,cant beat a manual overide system
