Decreasing power Ford Escape

Sorry if this is a repeat question. I posted this earlier, but don’t see it anywhere. My Ford Escape is now losing power when I drive up inclines. I can be driving 65 mph on the freeway, and then hit a point of incline, and I am down to about 50 mph by the time I reach the top of the incline, even when I’m hitting the gas hard. My AC wasn’t on either. I’m not talking sharp inclines either…just not a completely flat road. No lights have come on, and the car isn’t chugging when it’s doing this. I just changed my fuel filter by the way and used a can of Seafoam a few days ago. Pulling my hair out with this vehicle!

Additional info really needs to be provided before even a wild guess could be made.

How many miles on the Escape?
Any history of overheating and regularity of oil changes?
Problem come on suddenly or gradually?
Any Check Engine Light?
Do the RPMs seem higher than normal when this problem occurs?

There’s a number of possibilities but some may sound dire so I hate to go there at this time.

In your previous thread (, you told us about a diagnosis of a “bad catalytic converter”. If your catalytic converter is clogged, that could cause this problem.

ok4450: The Escape has a little over 120,000 miles on it. I haven’t had the car for long, just about 6 months, and there has been no history of overheating. I have been doing regular maintenance on it. The problem has gotten worse over this last week…yesterday was the worst. No check engine lights, or anything else abnormal going on. The RPM’s stay the same from what I can see.

VDCdriver…is there a quick and easy way to tell if the cat converter is going?
