First, posting two threads with the same problem will hurt your cause, not help you. Second, sounds like you are only running on one cylinder. What I would do is grab my heavy rubber gloves and my good insulated pliers. Start the engine and while running at idle pull one of the spark plug boots. If engine RPMs change that cylinder is working properly. Repeat on the other cylinder. If you have a change In RPMs that cylinder is not working properly. I would then suspect a blown head gasket on that cylinder. When you post back make sure you include all engine numbers so we have an idea of what engine you’re dealing with.
