Hello, the warning light you are seeing still warrants diagnostic testing with a proper diagnostic tool that will reveal a trouble codes related to your concern. Additionally, monitoring data with related systems is helpful in diagnosing the cause of your concern, regardless of any warning lights. Being that the vehicle utilizes electronic throttle control, i'm not too sure what benefit "cleaning" the throttle body will be for an electronic related concern.

The code is related to the intake manifold runner (IMR) or it's circuitry - which could have been damaged during the trial and error repair attempt .. Guessing at it ain't working out - so I too recommend *hands-on* assistance from qualified personnel.
