[s-cars] POS testing procedure

[djdawson2 at aol.com]

 Yes, changing positions on the POS is much easier than moving coils around.  If the miss moves, then you know what channel on what POS is shot... then you can use the unused channel to get back in business.

I've narrowed the misfire that manifested itself yesterday to cylinder #2 via 

pulling the injector lead and having no change in poor running. This morning, 

the issue was not evident on the trip to school with the kids until about 10 

minutes into the drive, at which time it was a total lack of fire on that 

cylinder, so I'm guessing it's heat related?  Back home now and need to isolate 

to coil or POS channel after I pull the cover to make sure it's not a plug, (the 

heat issue leads me to believe that's not likely).  Forgive me if this seems 

like a ridiculously simple question but I have a PM brain on technical staff and 

he hasn't shown up yet.  AM brain is not at all a viable alternative, especially 

this morning for some reason....maybe he has evacuated in preparation for Earl 

making landfall tonight.... anyhooo, what's the easiest procedure here? Pull the 

coil cover and swap two coils to see if the miss moves, or swap the POS plugs?  

The plug leads from the harness to the POS'

 s aren't long enough to just swap them from one to the other, so I guess I'd 

have to remove the POSs from their respective brackets and switch them?

Really, I'm not this stupid, but damned if I don't feel like it this morning....



Lil help?



Thanks...
