The sputtering occurs at 5000 rpm and above. I haven't driven the car
lately but may have stumbled upon part of the problem. I have a msd
ignition system, and I got to looking and I still had the hot line coming
thru the old resister which sits on the firewall. I bypassed the resister.
Like I said, I haven't driven the car since doing this. Could it be the
resister was starving the msd of enough fire? r dobbs
