A junkyard might be the best option if available

I installed this part on my 1989 Buick LeSabre. The sensor works fine, but after the car warms up from driving and you start it again (e.g. after buying it), the engine stalls very badly, making it rough and unsafe to exit the parking lot. It levels out after a minute or two. I wanted this sensor to replace the "Premium Gear" sensor made in China by WAI Global Transpo Electronics. I unknowingly replaced and threw away my original mass air flow meter a few years ago. You live and learn! It's…

Pros
  • Walker's Mass Air Flow (MAF) sensor measures air by weight by varying voltage or frequency
Cons
  • poorly thought out
