Car accelerates while parked.
My 300 is automatic. While my car is in park it accelerates and then returns to normal. It only accelerates to the 1 in the rpm. Another problem is when I'm driving, it doesn't shift when it's suppose to. It takes a while to shift by itself. I usually have to step on the pedal and then let it go for it to shift. Need help, info anything

Re: Car accelerates while parked.
Welcome aboard!
A few questions, since it sounds like you might be kinda new to automotive stuff - Does it eventually settle down to a lower idle (around 700?)
Let's start with the basics (regarding the transmission): When was the last time the fluid was changed / checked?
If the fluid is clean and full, and the filter is unobstructed, it could point to a vacuum line issue (which would also cause high idle). But let's check fluid level and color first.

Re: Car accelerates while parked.
Yes I am new to the whole car scene and car knowledge. And please forgive me if my questions seem dumb. Where is the dipstick located to check the fluid? When I open the hood there are two, one on the left side and the other on the right side. I'm assuming it's the one on the right side correct?
Re: Car accelerates while parked.
Transmission dipstick is on the left rear, right front is the engine dipstick

Re: Car accelerates while parked.
No worries - That's what we're here for.
Check both of them - oil should be between the H and L marks when cool, and it should be amber or tan in color. Black is bad.
Trans fluid should be clear/pink on a white paper towel, and it should be checked with the engine running, at operating temperature, in Park.
We'll start with the easy stuff!
