General Maintenance & Repairs - GTO sounds 'cammed' w/Video

For maybe 2 weeks now, I think the car has had a slight misfire at cold start. No codes, but the car sounds 'cammed' and shakes a bit. If I drive away then it goes away and idle returns to normal. :confused: The car has 51K, so I'm thinking maybe its time to change plugs/wires?

First check for any loose/dirty connections, that might be you only problem.
f the plugs have never been replaced then change them, but label each one so you can compare them all together. I'd also check to see how much resistance each spark plug wire has(especially if the plug for that wire looks like it was running rich), they should all be about the same. If you get any that the resistance is noticeably higher than the others it's probably bad.
Now if you still have the same issue it's either the coil itself, it's connector plug, or one of the wires going to it. I'd use a service manual for the exact procedure for checking a coil and its wires.
