Before you go replacing ecms..etc .pull each sprk plugs from its tube .if you see oil in any of 1 or all of them you'll need to replace the valve cover gasket amd tube seals .pretty easy to do . If oil is in the tubes it will cause a.miss because the connector to the plug is oil coated once started and a lil acceleration it will usually b urn off enough smooth out the miss ..while.driving it .. very con issue on alot of cats with speak plugs that got thru the valve cover ..Good luck
