Three questions - the first is if I park my car at night, then in the next day I want to start it, it is sort of harder to start up. If I leave the car for 30min and come back, the ignition is really fast, but in the other situation, it takes more 'time' that I have to turn the ignition before the car starts. Ideally it's maybe 500ms, but then the one that takes more time is maybe 2-3sec. Is this because the battery is going bad? I think one of the terminals is sort of collecting that crusty stuff, not sure if it is corrosion. I don't want to touch it in case it electrocutes me, so I'm not sure.
Second question - if I leave my car parked overnight, the next day, once the car starts up, I wait maybe a minute, and get into Reverse and go back out, and then shift into Drive. When I shift into Drive, the car makes this loud jerk, which doesn't sound good. If I leave the car to warm up around 3-4min, however, then the problem goes away. I checked the transmission oil (I don't know if this has to do with the shifting), and it's fine, the other fluids are fine, too. I wanted to ask what was causing this, what I should check.
Last question is, my uncle drove this car before, and usually when he stops at a long red light, he likes to shift the car into Neutral and told me it is fine. A friend told me if I leave the car in neutral it'll make something loose in the car. I assum Neutral makes the car work less. Does anyone do this when they reach a long stop? Is it bad for your car?
Thanks!
