1987 GN stalls after start-up..HELP!

[gsman]

A buddy of mine asked me to look at his 87 GN that stalls after start-up. The car is totally stock with around 77,000 miles. It has been garaged for about 4 years, and been started periodically once a month over that time. Up until recently it was able to idle, but it was very rough when it ran, Any help in this matter would be appreciated. Thanks. John...Buick **** member #567.

Most likely culprits is a bad MAF sensor or fuel pump. A scantool and a fuel gauge would help.

MAF is my bet
