Hauling my Cedar Creek fifth wheel home to MI from AZ I lost power in IL. Limped into Effingham to Northfield Ford. 2 hrs later they had diagnosed it as a plugged catalytic converter. Took a day and a half to get a new one. No charge. I wonder how many partially plugged catalytics are running around?

 

Interesting. Thanks for the info.

Was yours a sudden and dramatic loss of power? Or more of a gradual thing?

 

Now that I think about it, it seems like my mileage was getting poorer and downshifting occured on smaller and smaller hills. I'm thinking only a hundred miles or so. But, once I stopped I couldn't get going again.

 

Is there any way to test it?

 

If you think your cat is clogged, disconnect the exhaust from the manifolds and test drive. If considerable power is gained then you can put your money on the cat being bad
