URQ won't rev/misfires @ 4k revs

[Frederick Smith]

A few things come to mind. 
Inlet temp sender is bad or has a bad connection. Common cause of 4k cutout.
Wrong/bad fuel pump relay. I seem to remember that the incorrect relay,
	(one from a 4k/80??????) controls rpm limit on early non-turbos.
	The archives should help re:wrong relay installed.

The inlet temp sensor and connections has given me the rpm limit on a few
occasions.
