1999 Oldsmobile Alero Olds Alero rough idle


Engine Mechanical problem
1999 Oldsmobile Alero 6 cyl Two Wheel Drive Automatic 92,000 miles

I have a 1999 olds alero, with a 3.4L engine and had the Intake Manifold Gasket replaced, along with a tune-up. After I got the vehicle back, I noticed a rough idle. It starts just fine and runs fine at highway speeds, but just has a rough idle. I made sure all the plugs were tight along with the vacuum lines that I could see were connected but nothing. Obviously I am going to take it back and see why it is doing it. Right now the shop is closed but was wondering what would have caused this problem?

Do you
have the same problem?
