No... ping is advanced timing, too much compression, or
lean. You just put on an MPI... look for vacuum leaks, is
all I can think. You've got a sticky one... maybe try mixing
some av gas in?

Re: PING again. Tested Fuel pressure. Came out ok.
Every one of the Jeep MPI's call for 40 PSI until vacuum builds, then
back off to 30PSI. Hmmm... wonder how the new ones with the regulator
in the pump manage that?
