When driving the engine revs at a higher than normal rpm. It shifts gears with no problem(automatic transmission). It almost sounds like the choke is sticking, like on an older model car. It started doing it when the engine was cold, but now does it all the time.

Check for a stuck Idle Air Control valve and ensure coolant level in radiator is correct.

Check for leaking vacuum at intake manifold.

If the MIL is indicating, get a scan done to check for trouble codes.
