Does anyone know what the stock ecotec spark plugs are from the factory. I installed AC Delco Irdium Spark Plugs and my car runs like crap with no acceleration? Anyone know anything about this?
Stock isn't iridium, it's platinum.

So do you think this is my problem? Have you heard anything similiar.
Did you try to gap the plugs?
