Yes you need to buy an adapter and connect it to the fuel line. That's the only way. And if you can, get an exhaust backpressure gauge. That will surely verify your cat problem.

I'm actually taking it to a mechanic my friend recommended who has one of these big fancy machines lol. I'm only trusting my friends recommendation bc he usually does his own work as in depth as tranny builds, but if he hasn't got the time, this is the only guy he trusts to turn a wrench on his trucks.In the past we would hook up vehicles to a huge Sun diagnostic machine. It would show the firing of each cylinder, you could cancel each cylinder, and see the kilovolt readings of all 8 cylinders of the engine. You could see a spike in the cylinder that was acting up. These days Snap on or one of the better equipment manufacturers have it built into a much smaller unit. Still the tech working on it needs to figure out the origin of the miss.
