Clogged cats with forced induction?

positive LTFT means that your engine is running lean at that point. The ecm is trying to richen the mixture so it is increasing the amount of fuel to the engine. Remember that your front O2's are what adjust the LTFT. Not sure what, if anything a plugged cat would show on the front O2 reading.
I was looking at just replacing the front 02's until I realized they are almost $50 each! Jesus!
My LTFT used to read closer to zero at cruise and idle was lower, I think. Some of the jump might be the colder weather, but +15 at part throttle seems high, it could have always been that high though, i'm really not sure.

I can tell you for certain that my limit slip differential is still working. I have to drive up on 2x8's on all 4 wheels so I can get the front up on the ramps. Well there was a lot of sand on my cement driveway and when I went to drive up on the ramps the rear tires shot both those 2x8's clear down my driveway and the rear end fell 2 inchs instantly! That was nutz!

Does anyone know if the car will run with the MAF disconnected? I saw it mentioned in a 5.0 forum as a way to eliminate the maf as a cause. If it runs smoother, then the maf is causing it.

It should start and idle based on what the computer "beleives" it is recieving in air input.
Usually our MAFs will either completly die or function 100%. If your tune is off, I would guess weather (most likely).
