I had ordered a part from another web sight and it never came in so I ordered one from 1A. While I was waiting for the part to come in from 1A the part I had ordered from the other web sight came in one day before 1A's arrived. Next time I order parts 1A will get that business.
Problem solved!

Replaced my old MAF sensor for my 2000 Toyota Celica because I was having acceleration issues and it would rumble and stall at times. Now it runs smooth. I'm glad I bought this first before bringing my car to a mechanic.

Video was super helpful. Part was cheap and visually identical to the broken one. Garage quoted me almost $400 to replace this $30 part! It took me less than 5 minutes to fix it and all I needed was a Philips head screwdriver!! I don't even know what this thing does! I'm not a car guy, I can't even believe it was this easy

how does air sensor effect car performance ?
December 8, 2022

Im not sure it affects performance at all. It senses the air mixture and lets you know a problem exists. I purchased one hoping it was just a bad sensor. Not my luck though. The new sensor also told me I had a problem. Ended up being a leaking gasket.
