What is your question?
I believe it's a plugged CAT but my question...is there a way to know which CAT is plugged?

The guy with answer one is wrong. The escape has three cats. ther is one in the exhaust and there is one attached to each manifold. the one causing your problem is the one closest to the firewall. I only know this because I have an 04 escape that had the exact same problem. After much research I have found that the 01-05 all had the same exhaust and the same problem but ford will not admit the fault and send a recall.
Need to know if you have engine trouble codes. I can tell you this, you only have 1 catalytic converter in your vechicle. I recently worked on a 2002 escape 3.0 liter 4wd and replaced the cat. Solved the problem. When a cat. goes bad you can get sensor trouble codes all through the emission system from the back pressure and rough running at acceleration. Your cat. should be about a foot downstream from the flexpipe.
O'Reillys said there are 2 but the one right behind the flex pipe is the only one I see although the muffler does kinda look like one..lol. The only codes the thing has been pulling are a misfire on cyl 3 which I can't figure out because we replaced the upper and lower intake gaskets to cure a really rough cold start and idle issues and now the thing purrs like a kitten, no misses or anything but blew out the EGR valve, replaced it and within 4 or 5 miles it blew that one out too (blew a hole in the cast aluminum right where the internal valve seats). Getting too much pressure back to the EGR which popular opinion says is a plugged cat.
yes the cats are NOW plugged but because your engine has been running 240 degrees out of time. Go look at the coil packs on the front cylinder head- I'll bet you that your 4 and 6 plug wires are switched. They are labled COP 4 and COP 6. it's and easy mistake to make if you take all three of the wires off because it looks correctly connected either way and actually unless you read the little label it looks more correct the wrong way. Check the DPFE sensor to as it's likely to have melted down along with the to tubes off the EGR valve. and on a side note, unless you're really attached to the car I'd run it off a cliff as the three cats combined total cost and labor will total you a whopping $2000. a 12 year old car is unlikely to be worth that much, even in scrap weight
Those are the manifold catalytic converters, not the main exhaust catalytic converter he was asking about in a side chat.
