Again, I appreciate the continued support. Symptoms continue to get worse as the temperatures clime. I now notice a definite miss at idle now that it is “hot” (into the 90’s) and experimenting with gear selection can toggle the symptoms and can get the engine to miss at almost any speed with the throttle just off idle and very low engine RPM. The miss at idle is nearly un-noticeable unless you are obsessed with the problem. I got some time again this weekend (6/6/09) to do some more in depth troubleshooting and found the miss is certainly an intermittent, but possibly simultaneous, loss of spark to the #4 & #8 cylinders? (Note: the “entire” ignition system is new). I inspected, removed, inspected, cleaned, inspected, etc. everything from the distributor to the new spark plugs and all I found was some deterioration of the three connector ECM plug on the ignition control module in the distributor, which I cleaned, rebuilt and covered in heat shrink, to no avail. Measuring with a tachometer at ambient temperature of 70 and engine at full temperature there is no miss until RPM reaches ~1100 and the miss seams to disappear at ~1600 RPM, only missing on #4 & #8 cylinders????? I am all ears!
