[s-cars] //S4cylinder (#4 cylinder misfire)

[Mark Strangways]

Is it not possible to check the power to the coil and from the pos, and at 
the ecu and then at the coil while the engine is running ?
For that matter, if this is a regular problem, you should find overly high 
resistance in the #4 cylinder wiring from ecu thru POS to the coil. What I 
mean is the resistance of the wire only, i.e. between the ecu pin and the 
POS pin for example.

Sounds like a truly hard to fix problem, but I suspect your determined 
enough to find it.
If you have a scope.. but I suspect you don't.
