pressure gradient switch [5kT]

[Ameer Antar]

I was looking in the Bentley today and noticed that '85+ KH engines have a 
pressure gradient switch for cold accel. enrichment. Does the MC engine 
have one? [I couldn't find one in the book]. Would it be worth it to add 
the valve to my '84 KH? I've noticed that the car could use extra help when 
cold, but I have other cold-running issues. When I get down to replacing 
everything, should I add the gradient switch to the list? Ay 
recommendations on part sources, wiring, BTDT's? Thanks much.
