i believe it is TAS=Throttle Angle Sensor lol i thought it was weird but whatever lol take it off and hook up the compressor and blow all the carbon build up and shit out of it and there will be a lil screen pop it back in and it should be fine if not go grab some SeaFoam and suck it up through a vacuum line closer to the TB the better cause it will clean mroe shit, suck in a decent amount and then kill it by sucking in alot and let ur car sit for bout 30 minutes the longer the better then after 30 minutes try to start it up it will be a lil rough you will want to rev it up cause it will smoke but dont let it idle for about 10 minutes then u can rev it as much as you like *just dont blow your motor* and let it sit for 30 minutes or until it stops smoking you will have a pperfectly smooth idle and better throttle response
