I have a 95 lumina 3800. Lately it stutters while driving like a missfire...gotten worse lately.. THEN today start it up and it idles like new for 1 min ...then idles up and down like an idiot from 200rpm to 1300 for about 10 seconds and idles out fine then starts back up in the idles surges.. What would cause this.. I replaced all the plugs, fuel filter, air filter oil etc as it was required. I tried the paper clip scan but this stupid thing has the weird OBD I scan plug that can't be doen with typical OBD I gm scanners ($19 at parts store) so I can't scan it to see what it's problem is. Thanx for your time
