When I bought last year it had been sitting for about 8 months nobody could figure it out what was wrong and the gave up on it. I check Af and determined it needed a fuel pump so I bought it replaced it and all was ok execpt for the occasional stalling from time to time. Again after replaing a coil checked af and found the ignition switchs were common problems with GMC in 97 and I had all the systoms, dash lights cut out,stalling for no reason when ever no codes jiggle the key and alls well. Took it to the mechanic becuase I am always working and did'nt have the SPECIAL socets needed to replace it . Picked it up 2 days ago my wife has been driving it and said it's been good. Untill about 2 hours ago when she said it was sputtering and lacked power. She managed to get home in what I thought was a limp mode. when I checked it with my actron MAF came up. I erased the code drove it myself and it won't excellerate properly but idles great. What can it be? does it sound like MAF Im out of money and can't afford to guess or go back to the mechanic. Your help is appriciated. Oh yeah I cant type or spell worth a hoot .

Welcome to AF.
There are spell checkers that you can down load.
One upper right labeled ABC check mark under it.
On your problem 97 is a bad year on ign switches.
Is dash light still acting up and does wiggle switch/key still help?
Has fuel pressure been rechecked after fuel pump replaced.
What brand of fuel pump was used?
Lot of fails on Airtex pumps.
What was the code no that came up?
ANY OTHER CODES?
Was code cleared and recheck after driving and acting up.
When it acts up is it losing fuel pressure or spark or power from ign switch?
What all did the mechanic do to it or say what the problem was?
IF YOU HAD IT TO A MECHANIC I WOULD TAKE IT BACK FOR HIM TO RECHECK ON HIS DIME.
