I have a 98 Dodge Durango it will start and run sometimes and then others it starts spits and sputters and will die. It has black smoke coming from the exhaust pipe when it does fire. Backfires from times to time. Poor gas milaege.
Backfire is usually caused by a timing problem or maybe a fuel problem.
Hope this helps.
If you have not replaced plugs start there A bad map sensor will also cause black smoke and poor running

The first thing you need is to have the unit scanned. Check things like the baro sensor,map sensor,coolant temp. and the TP sensor.Also check your fuel pressure,volume and injector spray pattern. I think you will have found your problem,but if not hit me back with engine size and any codes,Good Luck.

Hi! I had the same problem with my 88 2.8 Ltr. Had dirty fuel Injectors. Put in fuel Inj. cleaner in gas tank, after a couple of days, runs like a dream,no more problems. Give it a try. Take care,Leo B. [email protected]

Breaking up like you described can be related to a condition where the distributor drive gear is wearing out.
Had you checked it for rotor tip
travel (about 5mm of loose travel is the max) or had the distributor
indexed? The indexing procedure appears to be similar to an ignition
timing adjustment but isn't the same.
Chrysler TSB
18-08-93 Rev A describes a condition often seen on the 1992-1993 3.9
engine. The distributor drive gear wears out prematurely and then
wallows out the support bushing in the engine block. Your oil pump is
driven by the same gear through the distributor shaft, so cold engine
operation often is worse from the higher viscosity of the oil and the
resulting load it places on the worn parts.
The distributor
index slips to the retarded zone (trails what it should be) just from
the gear wear. Adding in the worn bushing and chain stretch can put the
distributor in a position where ignition cross-firing can occur and the
switch plate (cam sensor) within the distributor can drop out-of-sync
with the crank sensor.
If you haven't done so, check this out for
me. Remove the distributor cap and twist the rotor clockwise and
counter-clockwise. The total tip travel should not exceed 5mm, which is
just about 1/8". Even if it exceeds this, an adjustment/ indexing of
the distributor will get it running right again if only for a short
while.

have you considered checking alternator and battery? just a thought
SOURCE: engine sputtered, then died. Towed home. I
Might be fuel pump, or filter is pluged up, best to chg. filter and then do a fuel pressure test.
