The key maybe the phrase "in our Florida storm".  Years ago I owned a

Toyota Corolla (please don't tell).  When ever the plug wires were

getting old and it rained the car rain aweful.  The problem is the wires

going through the valve cover.  When the humidity is high and the wires

are weak they would short out to the valve cover.  Great random loss of

spark causing a lousey running engine.  When you opened the hood after

dark you were treated to a wonderful light show.  Great show, no engine

performance!!

If your wires have 20k on the them I'd suggest trying a new set.  If it

doesn't solve the problem you can always take them off and save them for

when they are needed, they will be needed!



Good luck and let us know what happens.
