I cleaned the throttle body on my vehicle and now when at idle it fluctuates high low revs.

Good morning,

What did you use to clean the throttle body? If you use the wrong cleaner and it takes the coating off the plate, you could damage the throttle body itself.

Some of them are too harsh on the coating.

It sounds like you need to replace the throttle body.

Yes, you can. Make sure it is clean and not damaged.
