my car is having a similar problem its a 94 camaro with a 3.4. i checked my plugs and one wasnt pushed down all the way. when i pushed it down it started misfiring real bad. l looked a the plug wire and it was split and shooting a spark out and arcing off the engine. i replaced that wire and now it runs descent. The problem im still having is between 50 and 60 mph. when at low rpms getting up to speed it starts to sputter. idk what to do please help
