I'm having problems with rpms going really high even in park... When I press on gas pedal doesn't gain speed

 

Not enough information. But best guess is there is a vacuum leak and/or the throttle position sensor is incorrectly set.
Question is, even if someone guessed the correct issue, would you know how to fix it?
Take it to a mechanic that knows what they are doing and pay them for their expertise.

 

Yea, sounds like TPS, yet we don't read minds (cars or humans).,

Any engine codes?

 

It is very likely throttle related. A rodent could have ate through a vacuum line, a tps's wires chewed, or the sensor failed itself. IAC could be acting up. Throttle may be gummed up and out of parameters. They do weird things when no longer reading right. You have to start with a code scan and a visual inspection of the engine hoses and wiring isn't a bad idea if you know what to look for.
