Rough Idle and Sputtering
Ok so I have a 1994 buick park avenue and it would cut off while i was driving on the highway and the check engine light came on, I thought it was because the radiator was the issue so I replaced it. Then it stopped cutting off for a couple days, and then started cutting off again. Then I was told it was the ignition module so I replaced that and it ran fine and changed out the tensioner pulley assembly today and now it has a rough idle and the rpm gauge goes up to 1500 rpm and drops down to 1000 rpm but sputters. Anyone know or have an idea on what it could be?

Art, his 94 throttle body is different than your 97 throttle body. Matter of fact, both engines are pretty much different.
