a72z4me Posted December 28, 2009 Share Posted December 28, 2009 Hi Guys,first time posting on this site.I have a misfiring issue with my car(I think).I have a 72 240 with L28 bored 1mm,E88 head from 260,dual weber DGV's,ZX dizzy,MSD6 box,ZX alternator.It sounds like the timing is off but I have adjusted it from one extreme to the next with no change.The alt. gauge shows that it is overcharging(the alt. and MSD box are new although this problem existed before the upgrade).Could there be a short to ground somewhere causing the ignition to misfire?Any help is greatly appreciated Quote Link to comment Share on other sites More sharing options...
Two80z4me Posted December 29, 2009 Share Posted December 29, 2009 check the simplest things first, go get a new set of plugs, could be fouled, I had the same problem, and checked everything. Quote Link to comment Share on other sites More sharing options...
Mario Posted January 1, 2010 Share Posted January 1, 2010 Two is right check for the simplest things plugs, wires cap and rotor, some times the cap can crack inside and youwill never know it buy looking at it, some times the crack looks like hair.

302cobra Posted January 20, 2010 Share Posted January 20, 2010 I've had caps go bad and look just fine, run good for a month, then crap out and barely run for 2 hours or so. then run just fine for a few more weeks, then crap out again.
