I think you need new spark plug cables. Try this at night. You'll need a partner. Have them, with emergency brake on and both feet firmly on brake pedal, start car, put in drive, and give a little gas. Now while they are doing this, you should pull spark plug cords one at a time off of plugs. You should be able to see sparks jumping from the cable when held close enough to plug or engine block. I would almost bet that you won't see any spark from at least one of the six. Maybe two. You will need to cover up or pull out the little light bulb under the hood to make it dark enough to see sparks. No spark=need new cable(s).

bad need of a tuneup? like new spark plugs, ?
172 , is 02 rich/ lean warning. this one is low oxy for rich.
this code can just be a victim. for sure , with misfire.
means 02 sensor stuck at rich,
what is water temp in engine coolant, at failure? less than 150F?
could be lots of things.
leaking injectors, bad fuel.
injector sticking> causing misfire.
id use a scan tool and watch all sensor when it fails.
too high fuel pressure.
misfires cold, but only luke warm cold starts not fully cold.

just one DTC, no P0300 or 30x misfire codes, not even P0300 pendings?

My 1991 jeep comanche sputters when in 3rd at bout 3 grand.does it have a revlimiter?


no , but if in limp home mode (ECU) yes.

if the cel is out , running its not in limphome.

my guess? car was never tuned up, in last 60,000 miles or ever.

i had a 91 Comanche and ran it 250,000 miles, (5speed)

classic fails:

the bottom exh tube under my bell housing , the clamp breaks every 6 months ( i welded up a life time clamp) this allowed the

exhaust down tube, to flex and whole exhaust to act as silly pendulum. this put stress on my SST headers causing crackes.

this in turn let fresh air suck in to the header and slam the oxygen sensor to the rails, (car ran rich a s pig and could not keeps spark plugs clean.)

also the 91 has recalls on the CKP sensor. causing misfires.

its on the top left top of bell housing, very hard to see.

there is no scan tools for this Renix system. so can pull scan DTC codes, is your CEL glowing running?, BINGO.

my 99 Cherokee had none of this (well except sloshing fuel starves the fuel pump at 1/4 tank, design flaw.)



sputter is misfire.

the 91 does not have misfire detection in the ECU,

not till 1996.

so you are the detector.

do a full tune up.

then look at spark tips.

are the cream color or black.????????????

if black, post back.

i still miss and loved my Comanche. (im 1/8 real Comanche blood)

The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

its really a GM car, end to end.

no engines codes, is not true i bet ,
some codes take 1 to 3 trips, or dont store
and if you get CEL glowing, driving too much can clear the codes.
so.... that means you must scan it failing. see?

sputtering is misfiring (bad spark or way to rich fuel)

why do you jump all over fuel first.
try spark FIRST no gas engine burn fuel right with bad spark'
not one, and is first not last.
ever heard of tuneup, done one in last decade.
you know, spark parts? plugs and wire top list.

in the rules of basics its:
engine good, (compression test pass, and vacuum looks ok)
then spark
last fuel
why do that backwards/?

Car will not excellerate backfires then dies out. Chugging and sputtering. Sometimes acts completly fine. Clanking and banging coming from underneath the car.


Check the catalytic converter to see if it plugged by checking if exhaust flows freely out of the tailpipe when the engine is running.

Check that the plugs and wires are ok, and then go deeper by seeing if the coil packs (if equipped) are throwing any codes in the computer for a misfire condition.

Hope this helps!

Possibly the timing belt is wore out, loose, almost slipped a tooth - one of these. This missfire wouold lead me to this. When was the last time you replaced the timing belt? If it's over 80,000 miles have it done.
