I got my car in march and now I cant even drive it. When I put th car in drive, it will rev up relly far when I put on the gas and sometimes it seems like its in neutral and I have to swhich gears and put it back in to drive and somtimes in 2. I dont know if its my transmission or tramission fluid. I need yor help. Thanks

Check the transmission level and condition of fluid-also for the high idle see below

Too fast an idle speed. If an engine without computerized idle speed control is idling too fast and refuses to come down to a normal idle speed despite your best efforts to back off the carburetor idle speed screw or air bypass adjustment screw (fuel injection), air is getting past the throttle somewhere. Common leak paths include the carburetor and throttle body gaskets, carburetor insulator spacers, intake manifold gaskets, and of course, any of the engine's vacuum fittings, hoses and accessories. It is even possible that leaky O-rings around the fuel injectors are allowing air to leak past the seals. Another overlooked item can be a worn throttle shaft and a defective idle speed speed control motor/valve stuck in the extended (high idle speed) position/throttle position sensor. Also the throttle plate could be binding in its bore and kinked accelerator cable, coolant temperature sensor might not be operating properly misleading the computer that the engine is still cold and computer throwing fuel at it raising the idle speed

Thanks for the response. Is it expensive to have checked and fixed.
