Throttle Position Switch in 164L

[JimboMGA@domain.elided]

Hi there Alfa People,
I've been dinking around with my 1991 164L (autotrans) for nearly four weeks 
trying to fix a stumbling I get when pulling away from a stop.
The stumbling gets worse as the car gets warmer. Doesn't happen at all when I 
start out on my 10 minute commute to work. By the time the coolant temp reads 
170 the stumbling is starting to appear and after that it just gets worse and 
worse. Hotter=more stumbling and stuttering.
I've cleaned and checked tons of stuff already. This weekend I'm focusing on 
the throttle position switch or "throttle switch" as it is called out in most 
of my parts catalogs.
I cleaned the electrical connector for the switch and applied some contact 
enhancing grease. Now I'm wondering about inside the switch. What happens 
when you pull that little plastic cap off? I didn't want to go tearing into 
this switch to find out it's one of those things with little springs that fly 
out all over. Are there things inside the switch that benefit from having 
dirt blown out and contacts cleaned?
I've been trying to solve this problem for several weeks now. I'd be getting 
really frustrated if the engine wasn't getting so clean in the process. It 
just looks great!
Thanks much,
Jim Oiler
