As the title says, I'm having an issue where my car will rough idle after I get off the highway and return to city speeds. Stalled today at a red light, but cranked right back up and got home like normal. Just wondering if anyone can tell me the possible cause(s) and what I can do to fix it.
Top speed 80 mph on the highway and rough idles at red lights after going around 35-45 mph in the city. Normally rests at ~700 RPM, jumps to 1500, down below 500, and back up a few times. I usually rev the engine and it returns to normal, but today I let it keep happening to see what would happen and it stalled. Also worth noting; whenever I fill my gas tank up all the way, the car doesn't start normally. I have to wait 10-30 minutes before starting it up, unless I press the gas pedal as I turn the key (I don't know if that's bad habit or not, but it works). Possibly related?
