Your IMRC is likely stuck OPEN.. causing a severe loss of torque under the IMRC opening point.
No CELS?
I assume that means that they are physically gunked open (vice it being the controller I mean)
Personally suggest the following:
Check the status of your linkage. Look under the TB at the rod and linkage and see if they are stuck in an open position (rotated towards the firewall. Don't think that you can get your little finger in there and pry it closed.. if its stuck, it is likely VERY stuck (those are strong return springs) rev the car via the TB and watch for that cable and linkage to move towards the firewall.. if it doesn't (BOTH PARTS.. not one...) then you are stuck open.
follow the UIM/LIM teardown, going AT LEAST as far as the UIM, and clean up the secondary butterflies and linkage while on the car (don't flood the car with too much cleaner) (suggest tearing down LIM too, but still)
replace it all and see what happens. Either way, you could probably use the cleanup if you haven't done it yet.
