[QUOTE]Originally posted by bwkelley76: [QB] crazy thing... Mustang started running crappy the other day. It was acting like maybe the power valve in the carb (Holley 600) was going out. Every time I tried to give it gas under power it acted like a rev-limiter, like too much or not enough fuel was present. Everything except the carb (mystery item and kinda drab looking) is less than a month old including plugs, wires, cap, rotor, and ignition coil, so I decided to kit the carb. I already had a freshen-up kit on the shelf so thought it wouldn't hurt. Problem was still there! So I moved on to the ignition and realized the pertronix module did not match the coil I had (pertronix I and pertronix II are not compatible) so I replaced the pertronix module to match the better P2 coil. Still, didn't fix the problem! Actually made it worse! SO at that point I knew I had a secondary ignition leak somewhere so I swapped out the cap and rotor for a known/good one. That didn't fix it either. I finally looked at the wires and plugs a little closer. The plugs at first glance looked PERFECT. Sure enough, with a closer look a few of my month-old spark plugs had trails on them and were arcing to ground along the electrodes instead of jumping the gap. VERY MINOR and hard to see traces were found on 4 of them. I got a bad batch I guess. NEVER had a problem like this with an autolite. So I replaced the plugs and all is well. She runs great again. ...In all my years I've never had one of my own cars suffer from spark plug arcing and I've always used autolites. I've had customers' do it with old/used champion and other brand plugs but never mine. Guess my number was up! lol [/QB][/QUOTE]
