and having a hard time finding one for that cheap

It’s a 2004 model , 1236 4 cyl. 4 stroke , fuel injected w/ turbo. I have cleaned the spk. plugs, and even baked them in oven . After this is done , it fires right up and idles fine w/ no smoke. A stab or two at the throttel smokes a bit and foules plugs. What did i do ?
