Re:  Missing at idle

If the engine runs just fine in traffic and going  uphill, the fuel 
pressure must be okay. It sounds like your only concern  is the 
missing at idle and popping when you take your foot off the  throttle.

You're probably right about the popping being due to exhaust  leaks, 
but missing will contribute unburned gas to the exhaust stream.  That 
only makes sense, however, if you also have missing under  load.

Is the engine missing while you're driving?

For the  missing at idle, I'd look very closely at the ignition 
components. Use an  inductive timing light on each cylinder in turn, 
to see if one of them  fails to flash occasionally. That might point 
you in the right  direction.
 
I'm wondering if the wire lead for the CHT is too close to #3 plug  wire. 
I've heard that this can happen and cause a miss.
