1996 Chevy Camaro MAF low current trouble code

1996 Chevy Camaro mileage: 97,000. I recently bought this car for my daughter and do not have any maintenance history on it. It appears to have been well maintained and mostly driven on highway. My problem is that I get a MAF low current trouble code and the car stumbles/bucks badly as soon as I try to accelerate. If I clear the code, it comes back immediately once running temperature is reached. I have checked for vacuum leaks and for bad electrical connections but have found nothing. The engine starts easily and idles smoothly. Any suggestions would be appreciated. Thanks.
