can't exceed 25mph after rain.. getting worse

This problem started out only on days it rained or was really damp. Escape starts rough... then take it out on the road and cant climb over 25 mph. Took it to a mechanic who replaced both of the cats, as well as did a full tune up and oil change. Escape started running better.

Then we got a weeks worth of rain.. Escape wont run over 25 mph after start up, and the mechanic cant find anything else wrong with it. Computer tests shows the escape is happy as a clam. Even though the weather i warming up and drying out, this problem isnt fixing itself as it has in the past when things dry out.

Any ideas??? cant afford to put too much more into this!

Thanks

Sounds like your CATs are clogged again. This happened to me 2 weeks after getting mine replaced so it's not uncommon. With your car running, check the backside of your engine where your EGR valve is located. Is it making a hissing sound or is it VERY hot? If so then your cats are as poorly clogged as mine were.

My cats went twice and the dealership spoke to the Ford engineers. They found out that it was a computer problem. The computer was allowing too much gas to go into the cats. Which caused them to clog. The computer was replaced and so far we haven't had a problem. The car is running great. The computer was covered under warranty.
