This article is from the Chrysler-Plymouth-Dodge FAQ, by Dr. David Zatz with numerous contributions by others.
Problem: 1992 Dakota 4x4 with Magnum V-6. Engine faltering badly
sometimes when cold, sometimes when hot. On cold starts, the engine
will sometimes act as though it's getting gas only at idle, won't
accelerate.
It will cough and sputter awhile, then "catch" and take off, running
fine from then on. Other times, it will "skip a beat or two" at speed,
under mild acceleration.
David Wright: Some Magnum engines came with "mis-phased" distributors,
causing intermittent missing.
Jerald Barker: Replace the back pressure transducer and EGR valve. The
Back Pressure Transducer lies next to the EGR valve just above the left
valve cover.
