20 years ago I had a particularly nasty little hot weather stumble trying to accelerate off at the lights in my old P76 on gas, and all the usual fixes were applied. It wasn't until I swapped out the relatively new Top Gun leads for the Bosch leads that the problem disappeared forever, leading me to look for a rational explanation. I've since met the problem across a range of vehicles (including D2's and P38's) and high resistance leads generally fixed their problems. Thanks to Mario (Roverlord) for supplying a few sets of OEM leads.
