Check your power valve?

Don't be afraid to put patches over patches too. I'd fix it. Maybe 3 patches, each larger than the previous.

Bone stock 2001 pathy, bought to get thru winter and teach my kids how to drive. Very nice vehicle, but I got screwed on buying it. Good price, but needs more work than expected. So far, I like it, and I'm getting nearly 20mpg.

My poor pathfinder has no power over 3000rpm, I checked my power valve, it's ok. No vacuum leak s. When WOT, I'm reading about 4lbs of boost in the intake. Sounds like cats are bad. I also have a cel for bank 1 sensor 2 o2 sensor. I ordered a pair of precats, can anybody tell me how hard they are to change? They look like a real pita, but are they bolted, or have studs on the manifold? On a level of 1 to 10, how bad are they? I have a decent garage, with everything but a lift. Thanks all, Len 2001 SE, bone stock and fully loaded. Parked on grass by po, so some surface rust underneath 14x,xxx miles. automatic.
