BUICK LA CROSSE CHECK ENGINE LIGHT PROBLEM

1997 Buick La Crosse • 120,000 miles

Have a 97 buick lesabre, check engine light came on about a month ago but was running fine had a friend check I with the computer he said it was throwing an egr valve code. Few weeks went by the car started to shake or stumble at about 35-40 mph when letting off the gas it stops also does this at 60 with light acceleration (to hold current speed) We took the valve off and cleaned it then put it back on and cleared the code. Still is happening. Went a bout a new valve car ran better for about 5 min then started to do it again please help (don't have much money to start replaceing a bunch of things!

What is the code number? Codes never identify bad parts, just failed systems
