Kh boost/ list traffic.

Todd, try posting one time for all your questions, please. I'm sure many
don't appreciate the traffic generated by 5 one line questions in response
to the same post.

About the fp cutout-Those cars must have been malfuctioning... all of
them. I find it hard that you've found all these people with good info. My
car, as well as another shows 1.65 bar on an external gauge at cutoff,
going along with the factory service training manual I had.

According to parts sources, the 84 was one year only. I find it hard to
believe that the 84 kh can't fit the 85 kh. The kh head can't fit on an MC
2. For the mc 1, I can't say for sure, except parts crossovers list them
as non interchangeable.
