Exclamation a couple problems with my '97 civic pls help

Okay, so this is my first time doing this whole forum stuff, but here we go.

So I bought a '97 Civic auto and have almost had it for a year now, learning what's under the hood and everything mechanics (first "project" car) and it's been having a couple of problems since I bought it. The first thing is I'm having high idle. Now I researched about idling for civics and the main things to look for are vacuum lines, throttle body, sensors, etc. I replaced the MAP sensor (the check engine light went off after that), cleaned the throttle, and checked everything "air" related and it's still idling. Now the second thing is rattling, when I turn the car on I can hear some "rattling-like" sounds around the passenger side and it's been like that since (might be the motor mounts but I'm not sure). Another thing is an oil leak, but it's pretty self-explanatory (I got this one haha). And the last thing is my gas hand showing inaccurate readings (let's say I filled up my tank on "half", it would go up and back down then sometimes on "E" when I'm driving), haven't seen much talked about this topic but if anything let me know.

I tried taking it to the mechanics and you know how that goes, charging an arm and a leg to do something minor haha, so I figured to get on the forum and see if anyone out can help so I can hopefully fix the problem myself; it'll be much appreciated. Thank you!

ps: even if you don't have a solution but just tips or words of advice just reply also I would appreciate it! any questions let me know!

hello, welcome to the forum. the high idle issue sometimes can be a bad ect sensor or thermostat. if your vehicle is taking a while to warm up or the coolant gauge isn't working, this could be an indicator for this. it could also be an ignition issue and could use a "tune up" meaning new sparkplugs, wires, and distributor.

the rattling when startup sounds like exhaust. i know my flexpipe on my cavalier would rattle on startup. if you hear something like a rattle from the valve cover on start-up and it's a v-tec motor, it could be the v-tec actuator.

i have zero clue how to handle the gas gauge showing an inaccurate reading.
