Do i need or have to change the egr valve on my 94 transport 3.1 before our trip?

Hi ,a couple of months ago a friend did the test and found our engine

light was on because of the egr valve. we are going on a trip in two

days, and dont think we have time or the money to fix it before we go.

the van is running fine exept for the light being on a few minutes

into driving. Should we expect any problems or should we hurry to fix

it? Also how hard is it to replace ourselves?Do i need or have to change the egr valve on my 94 transport 3.1 before our trip?
You could take it off and clean it. That may do it. If you have the time, I would go that route. If not, then take your chances. I doubt if it will cause you any problems other than a little rough idling. Good luck.Do i need or have to change the egr valve on my 94 transport 3.1 before our trip?

the way i fixed mine was, i unhooke the battery and took the egr valve off and took some carb cleaner and a wire brush and cleaned the bottom of it, when you clean it, make sure the those little pintal on the bottom isnt stopped up with carbon, and watch you dont tear the gasket. put it back on, after you dry the carb. cleaner off, then hook up the battery. thats the way i did it on my olds.
