[Supras] Spark plug wires at 18 PSI

[Dm19959 at aol.com]

Understood. Car idled OK with the stock wires but still had the occasional  
"miss" in the exhaust note at idle. That went away with the MSD wires  simply 
because I think that they can ignite a slightly lean mixture better than  the 
stock wires. Other than that, no problems so far.

    At 18 PSI I can understand  that due to breakdown voltage requirements, 
you might have been better off  with MSD wire than carbon.  My experience at 10 
PSI was different, as  stated in a former posting.  However, my Supra has 
always idled so  smoothly with carbon wire that a nickle could be stood on edge 
on the engine  and not fall over (mine is a '90 with a fully counterweighted  
crankshaft).  Spark gap breakdown voltage is low enough at idle that any  spark 
plug wiring should work unless in very poor condition.  But,  apparently each 
of us have had different experiences.  Such is life, and  any of us on the 
list can offer only what experience has shown  us.
