1) Our engine monitor (JPI EDM-700) sometimes indicates sporadic EGT
values for #1 cylinder. It behaves like a sensor or connection issue as
the engine runs fine and the fuel burn is within expected values. #1 CHT
value dances up and down fairly rapidly +/- 25 degrees or so of the value
as compared to the other cylinders. The value changes fairly rapidly
(much more so than with the other cylinders). The problem has come and
gone consistent with some sort of wiring issue. Anyone seen a similar
problem? Engine is IO-360.

Follow the wiring for the #1 cylinder from the spark plug to the firewall.
We had a similar problem with our #2 cylinder, and it turned out to be a bad
in-line connection/splice. An easy, ten second fix.

2) Right brake pedal travel is noticeably more than the left. Stopping
power of both brakes is fine and the fluid level is only slightly down
from the full line. Applying the parking brake while rolling causes the
plane to slightly turn left, consistent with the left brake applying ahead
of the right. No hydraulic leaks anywhere that I can see. Could it be
air in the system that needs to be bled?

I've had the exact problem, ever since my last annual, when we replaced a
brake hose. I've had my A&P bleed that brake three times now -- each time
it gets a little better -- but it's still not quite "right." Bleeding
Cherokee brakes properly is a real bitch, involving more than just bleeding
the system down at the wheel. You have to get under the panel, stand on
your head, and bleed the system under there, too, resulting in the
inevitable brake fluid on the carpet, etc.

It's not a great system.
