Frozen Throtle Cable???

["dmc_delorean_2000" <dmc_delorean_2000@xxxx>]

hi
Although its april the weather in NY keeps getting cold. If I dont 
use my car for a day or to and its freezing temp outside, my gas 
pedal wont budge. in the engine compartment the throtle moves freely 
but the pedal wont move. even if i let it warm up with the heat on 
the gas pedal just wont move. i can rev the engine from the throttle, 
but thats it. anybody have any suggestions to fix this dangerous 
problem?
Thanks
