    M50NV Running rough

    Completed my M50NV swap a few months back with no issues until now... after 1 or 2 minutes after I fire it up, it starts to run rough like its rinning on 3-4 cylinders. It does not pull when I give it some gas and car shakes from engine vibration and I smell fuel from exhaust... any suggestions? I'm thinking its coilpacks or something. How do I check if they are good?

    remove the engine cover during the night, then watch the coils and see if you see any sparks

        Check your coil packs.go to harbor freight,they sell a spark plug adapter kit. It's like $10 or so,that way you can lay the coil pack and plug in the extension..you can see if the light light up..sorry I'm tired
