That is a fine product and works well, used some a few months ago on our daughter's 02 corolla high school car, it was having slow throttle response and pausing while accelerating and this cleared it up. The MAF sensor did not look dirty or grimy, but apparently they can have gunk that you cannot see. A few sprays and let it dry and done, runs like a champ. Super easy and cheap, since it is a 2 pack I cleaned the TB as well. have used product for years but only recently noticed the 2 pack. The 2 pack is cheap enough, I do it every couple of years on our other vehicles. A shop would probably charge $100.00 to do that task. The way I look at it, it is only about $8.00, so that saves me $92.00 that I can spend for other household essentials like beer and ammo.
