I do not know much about the Ford Coil pac\ EEC and it's fuction,so is the following statement applicable to our 2.5 V6 engines? It was a response to the old question of do platinum plugs blow out with a blower setup:
"Some of the multi-coil ignitions are a waste-spark type, and fire on the exhaust stroke as well. This means the plugs fire twice as much. To make things worse, the second spark goes in the opposite direction, so they get hammered from both sides. That's why some of them are dual platinum."
I do not have forced induction or even a K&N... My question was generated by the fact that after my E-test yesterday on the 1996 "Tour, reading's of 0 HC ppm and 0 CO%. The NO ppm was 230 of the 518 limit.Pretty clean for a 125K Km car with the original plugs and all......it also sat for 6 months and ALL I DID was new Fram air\oil filters and fresh Quaker State oil....I'm amazed
Comments?
Thanks
Bill
