2001 Honda CR-V bad gas cap - automatic reset code?

I have a 2001 Honda CR-V that I need to have a smog check and the check engine light just turned on. Previously, the code was for a Gas leak, so I re-tightened the gas cap. Again, the check engine light turned on and when I got out of the car, I smelled has fumes. Checked the gas cap and the o-ring has a crack.

I do not want to reset the code, due to not wanting to complete a full drive cycle for the smog check. Will the 2001 Honda CR-V automatically erase the code when it senses the problem has been fixed? Or does this car require me to erase the code manually?

When should i use overdrive?

I have a 2000 honda crv, its a 2.0 L 4 cylinder car, its underpowered for its body but it gets around pretty well, i get terrible gas mileage for what it is, I live in a pretty hilly area and my rpms are constantly shifting up and down, should i turn off overdrive when going through these hills to conserve gas?

Why is my gas mileage so bad?

I have a 2000 Honda CRV and I'm almost just giving up on this car, I love the SUV but I no joke barley get 200 miles to the tank, with this mileage I could be driving a truck or a Toyota 4Runner (which is what I really want), I changed and did the following: air filter, fuel filter, inflated tires, O2 sensor, rebuilt transmission and catalytic converter. The spark plugs and timing belt are fairly new and in good condition. I have invested enough money in this car to last another life time, I even took this car into firestone to check what was the deal and they said the car was in great condition, I understand this car is 17 years old but its only a 4 cylinder and in good condition

I'm 14. I continually make up stories about a Honda CR-V - 1

None are true but I can't help myself. Posters move my posts to the mental health section but I move them back because I'm sick. Everyone should know.

Added (1). When these heathens began to crack on me for being a 14 year old troll, I pretended I had a civic.

But for some reason, they still did not believe me. Why do these grown ups pick on me for pretending I might have a car one day?

Added (2). My mom said I might get a permit by the time I'm 30. So in just 16 years, I could get a learners permit.
