1982 imperial acceleration and valve melting problems!!!!!

["Ivica Dropulic" <ivicadropulic@xxxxxxxxxxx>]

I have a 1982 Imperial and i have a few problems.  First,  it has a problem 
accelerating,  when its cold its okay,  when it warms up,  and you floor the 
gas,  it takes a long time to get up to speed,  but if you press slowly its 
better.   Also,  what is that valave that is attached to the air pump.  i 
replaced it once and put another one on and it melted the same day.  Does my 
imperial have two catalitic converters,  could one of them be clogged?  
Could that be casuing both problems?
