MASS AIR FLOW SENSOR

1999 Chevrolet Astro • 6 cylinder 2WD Automatic • 143,000 miles

I have a 1999 Chevy Astro LS with 4.3L. I have burned up 3 coils in the last 8.5 months; last one only lasted 9 days. My repair shop is saying that my Mass Air Flow Senor is bad; running lean and causing the coil to overspark and burn up. I will install new MAF sensor as soon as it arrives and then have them replace coil again but is really the answer?
