[T3] Weird Idle Dips

[Dave Hall]

Check the distributor is firmly clamped - it might be your timing is
gradually changing.  Is the distributor cam lubricated?  Could be the points
heel is wearing quickly.

I assume you don't change all the components each tune up?

What do the plugs look like when you take them out?  There might be clues
like oil or soot that show there's a problem outside the ignition system.

Subject: [T3] Weird Idle Dips

On this subject, I've had an annoying problem in that every time I do a tune
up (points, plugs, cap, rotor, condenser and valve adjustment), my idle is
smooth and clean. After a few weeks it starts to have a weird stall dip at
red lights. Only longer lights. Then by the next month, my idle at
stoplights becomes rougher, with a more frequent miss in the idle, until I'm
tired of it, then I do a tune up again and get the smooth idle. Is there any
relief or escape from this creeping miss problem, or is this just the way
the cookie crumbles?
