I bought this part for my 2001 Buick Regal LSE after messing around with code P0171 and one day I got P0132 (low voltage on mass airflow sensor). I started splashing while accelerating and accidentally shutting off the engine. My car is 148k and has been well maintained but these issues have bothered me. I replaced the fuel filter (much expired) which was dirty (lesson learned), I replaced the "bank 1" sensor; and FINALLY found an intake leak 'after the MAF sensor but still had a 'chuff' and occasional hiss. The 'throttle body' was also Hitachi, the choice was obvious, THIS is the right part for this application, it arrived FAST and installed just as quickly (2 screws and swapping the "plug") "Harbor Freight" is your friend for those "secure torx" connectors you need (at least for Buick . Easy to fix and out of the past. No more chugging/burping and stalling, NOW when I press the gas pedal for the light it's BALL*TO THE WALL acceleration, great part and great service from AMAZON. Thank you very much
