I have a 2000 SE Zetec and I've been going around with my two Ford dealers around my parts saying I'm crazy. But since I have become a CEG'er. I may not be crazy - I'm having not a miss but a lack of power when I go up slight inclines.The car runs smooth on the flat or ,of course downhill, but when it starts going uphill at all, more of a "load" it seems to have a tendency to "miss" occasion. Could you tell more about the plugs?? I replaced mine with Autolites and it didn't help. Do you think it could be the wires instead???
