On a 2011 Chrysler 200 what is an electric throdell light for?

Well when my lighting bolt came on ; my car slowed down I tuned my engine off for a minute and it started back up ......I had to replace my thermostat chrysler hit me for $600....and the part was only $30 to $60......

Its the throttle control mine is having this issue now

Had same problem cost 800 for throttle body if your having this problem go slow I had check engine light come on couldnt exselerate to pass it would chug like u downshifted and wouldn't go past 2000 rpms and them lightning bolt light came on then went off code read I have multiple misfires on number 2 sylander so I changed pluge didn't help I changed all for coils no help I changed the variable timing thing no help so took it to shop cost me 800 i get it back all good the next day same problem misfiring on number 2 called shop they said bring it back in the next day well i decided to check out a theory i had went to auto zone and returned my four coils bam runs better than when i bought it 1 of the new coils were bad so if ever u are stuck on your 200 hit me up i know this car front to back
