1995 Cavalier Z24 Surge

About 2 months ago, I replaced the sparkplugs on my Z24 because they were the cause of some surging. The problem has come back and I was wondering if anyone knows of any recalls or problems with the 1995 Z24 ignition system that would cause the engine to start surging again.

Please help.

Check For Vac Leaks. Definitely Check The Egr Valve.
