Temporary rough running
My '94 with 2.3l, dual ignition. always starts reliably...runs good and smooth for a minute or two...then runs really rough for a minute...then smooths out again and is fine. If I start driving "before" getting through the rough time, the engine will bog down and backfire for the same time....not a good thing while driving. Other than this problem, the truck is great and runs reliable, Anyone have any thoughts about what might be causing this momentary roughness?
