Maf???

[thelhb]

Went to lunch today and while driving down the street my normally good running 87GN died. The car will start and idle rough, but when when I try to accelerate, I get a check engine light and the car just dies. I was able to limp most of the way back to work at 2 - 3mph. Just before I arrived at my job it ran normally for a block or two then began to sputter again.
Could this be the MAF or TPS?

Relitively new to the G body game, please help.

Thanks in advance

Could be the MAF, could also be chip/ECM related.

What code(s) did it store?

another possibility is a hose came loose in front of the throttle body somewhere. Happened to me that the hose pulled off the throttle body (intercooler flapping loose pulled it) and I had those same symptoms.
