[QUOTE="buschpoweredstroker, post: 73911, member: 1426"] duh, it's coming from your distributor or you don't have R rated plugs!!! jk... does the interference change pitch with the RPM? If yes, the resistor diode in the alternator may be at fault... Low voltage can also cause your engine to run rough. If the pitch stays constant regardless of RPM, it may be related to the fuel pump(you will hear interference with just the key on while the fp is running), blower motor(if that's it then it will change on various speeds), or it could be related to a short somewhere... my guess with the rough running correlation is that you have an under valve cover harness(UVCH) short which is causing the intermittent rough running. Also I've heard you shouldn't run to the battery with the ground, the closer to the battery the better with a shorter wire. hope this helps [/QUOTE]
