Hang on -- if the DPR current is non-fluctuating, it means the computer is 
in limp-home mode because it's missing one of the inputs needed to 
determine the correct mixture -- O2 sensor reading, temp sensor reading, 
whatever.  So first find out what's causing that.

Secondly, your air plate should move easily and smoothly.  The engine not 
responding when you hit the gas sounds like it's running very lean.  That 
makes perfect sense --- if the plate is sticking, it's not getting enough fuel.

Lube the plate, find out why your car is in open-loop, and go from there...
