I would have it checked to make sure no error codes and then suggest only having the IAC it uses checked or serviced-----Idle air control exists in many drive by wire vehicles--have a physical throttle and or cruise control cable-----the start is Google this year model with IAC symptoms.

They get dirty or fail and all sorts of idle issues are possible

is this engine cold or hot.
why is 2000 rpm wrong for 60mph., (depends on engine and axle size and what gear you were in , then)

the idle speed for hot is too high
did you scan the PCM yet?
if hot , idle is high, is the thermostat holding water temp 180f or above. ? if not that is the problem.

My 2001 grand cherokee started to high idle all of a sudden, close to 2000 rpms. Where should I start checking??


Check for unmetered air entering the engine usually from a vacuum leak. Check all hoses to make sure none are disconnected/collapsed/leaking vacuum under the hood. If all ok, possible idle air control motor sticking resulting in high idle

Stays at a high idle when driving and stoping


Check your idle air control. If it does not work properly, it allows extra air into the engine and brings you engine RPMs up.

Maybe the Throttle Position Sensor (TPS) if the computer thinks it is all the way to the floor then the gears would not shift until the engine RPM is real high. Also would not be able to determine the car is supposed to be idling. Do you have a check engine light? If you do this may come up on a scanner.

I had the exact same problem on my 04 GC. I put some Techron Concentrate Plus Fuel System Cleaner in from Wal-Mart and it seemed to fix the problems right away. Let me know.

High speed idle


You have either a vacuum leak or your IAC (idle air control) motor is stuck.
No service engine light on I assume.
Let me know.
