Re: 02 Escape no power
A clogged cat converter will increase back pressure and cause the vehicle to operate in what's known as a fail safe mode, which is generally first gear only and at low speeds. If you can, get a second opinion about the manifold gaskets as the mechanic that you mentioned in your last post doesn't seem to sure what's really going on. I don't know if the price is good or not, but anything over $1K in price is definitely high and worth seeking a second opinion.
Lastly, is the engine throwing any codes (lights on dash)? If so, reading the codes will help pinpoint the source of the problem.
