Wow that was exactly what my friends dad said.Sometimes you just need to break down and take it to the dealer. They have way better diagnostic equipment, once you know what it is. You will be able to fix it yourself. The plugs smell rich because u have unburnt gas. Coilpacks need a scope to test.
Im going to examine the cat and see if its clogged. If thats not the case im raising my car and driving it to the dealer
