Tuan, I cleaned my TB today as well. It's easier if you unscrew both clamps of the tube and remove it from engine compartment. First time for me. Replaced MAF sensor with OEM ($75 from AIP Electronics) as well and now my car idles and accelerates more smoothly. Cel off now and I am a happy camper after a drive through the Texas countryside. My only wish is that I could get 45 MPG like my VW Jetta TDI.
