Had a weak airflow sensor in my 2003 suburban ( would trigger code every so often clean it it would be good for awhile) decided to try this sensor since it was cheap ... put new sensor in within minutes truck was running terrible and tripping several codes.. reset and tried again same issue put old one back in and no problems drove truck from texas to Florida back only triggering old code once ... replaced with ac delco maf sensor havnt had a issue since ... I will say seller was very responsive and offered refund or replacement right away but did say could be my 02 sensors ..hmmmm no issues with new sensor..need to check with your manager

Went nuts troubleshooting why I still had a MAF Check Engine Light after replacing this item, and eventually took my vehicle to a mechanic who determined the sensor was bad and charged me $150 + labor to replace it. Truck runs great now and no Check Engine Light. Unfortunately I waited more than 30 days so unable to return.

My engine light has not come on since installing it and code is cleared. Time will tell if it lasts. I think it's a good part for the price.

So far so good. It replaced one that was much more expensive OEM part. That one lasted less than a year with no real reason for failure. Just hope this one lasts longer.

Fits my pick up and increased power. Not sure on gas mileage yet, will update later.

My husband installed this on his 2003 Chev Avalanche due to a check engine light and stalling issues. Since the installation (about 2 weeks ago), the truck seems to be running fine. I'll update this review if anything changes, but right now we are happy.

Great to begin with, then rough idle, etc. within just an 8,000 mile year.

This eliminated the MAF performance code being set by the powertrain control module.
