[s-cars] miss at idle

[Matthew Russell]

Dave- thanks for the help.

I swapped the 123 POS to the 45 side, and then rewired both the 4 pin  
and 3 pin connectors on the suspected bad POS (now installed on the  
4-5 side so that IIRC cyl 4 now uses the rh side of the 3 pin  
connector and cyl 5 stays on the lh. (I may have mixed up which is  
where, but you get the idea) bypassing the "center" channel of the  
suspect POS that used to drive cyl 2, the one with the missfire.

I actually used the directions from Charlie's site near the bottom of  
the page.

Drove the car to work today with the #2 fuel injector unplugged to  
decrease the amount of unburned fuel going through the combustion  
chamber and into my cats. Now I have access to a spark testor which  
shows no spark on # 2. I had already swapped in known good plug and  
wire last night so I guess that leaves coil or wiring. I'm hoping coil.

Anything else I'm missing?

Oh and Bob, sorry I couldn't cc you this, stupid lack of cut n paste  
on iPhone.
