theres 3 problems ;[

1. something happened last week, but i ignored it till today.

when my foot was on the gas at a steady 40mph, for some reason it felt like i lost power. i didnt let take my foot off my gas either. so i would be going at a 40mph rate and couple of secs later it goes down unless i accelerate.

could it be my fuel?

2. when i start my car
my idle jumps up and down btw

900-500 rpm.

it would go away if i gas on it once though.
idk if its a common thing or a problem.

3. today while driving. i notice whenever i gas it over 2.5k rpm. my water temp meter does down. and when i let go of the gas it goes back up.

heeelppp pleaseeee
