I just finished replacing the front cat on my 2002 3.0L escape. It took me about 4 hours. Part of that time was driving to the store two bolts and for a new O2 sensor (peace of mind).
First you need to remove the bottom plastic engine covers, both sides. Disconnect the battery. This will reset the computer and remove the "check engine light". Next to make room for your hands and tools, you need to remove the radiator. I know it sucks, but you just can't get tools in with it there.
Drain the radiator and disconnect all the hoses and electrical connections. I plugged the transmission coolant hose with a Golf tee. Pull the radiator out. This will take the most time of the whole project.
You can now gain access to the 6 nuts that need to be removed from the block. Use a 13 mm deep socket to remove them. You will need to remove the top O2 sensor to gain access to one of the nuts.
With those out, remove the two nuts holding the cat on the exhaust. This is on the bottom of the cat. You will be able to remove the cat as this time. Remove the old gasket on the block.
Reassemble in reverse order.
Cost: I bought a BOSAL front catalytic converter on line for $311 at RockAuto. The price ranged from $1200 (repair shop est) to about $450 local auto parts shop. Gasket cost about $7. You will need antifreeze and maybe two bolts($2 Home Depot) to bolt on to the exhaust.(my Bosal didn't include them)
Not hard, but does take some time. Radiator removal does take the majority of time. If your code was a p0430, then the O2 sensors should be good. The sensors run about $45 each if you want to replace them anyhow.
Good luck.
