June 30, 2009Still trying to figure out an intermittent problem with my 89 351. It still seems to be lacking power and occasionally misfires under heavy throttle. Has new plugs and coil and the wires and cap are a year old (not installed by me). The wires are touching the heads in a few spots and I'm just wondering if the wires or the cap and rotor could be causing this... or if the cap was installed improperly if the timing could have been thrown off? Looking for any ideas here. Checked most of the sensors already and they seem to be good as far as voltage goes. Thanks guys!
