i own a 93 4x4 dakota and when you hold the truck at steady speed you can feel a slight hesitation or surge. dealer ship said tranny was bad, but it shifts smooth and fluid smells fine, and it dont slip or nothin....i think it might be a sensor or filter going bad but i need suggestions....thanks

i have a 99 r/t with the same problem. Tried new trannie fluid, new ecu, tuneup, octane booster, f/i cleaner (professionally done), all to no avail. If you notice that it is happenning at around 2000 rpm at exactly 60 mph then its the same problem i have that the dealer said was in my mind. good luck.

I just had the trans replaced in my 94'. The local dealer was booked for a week so I dropped into a local tranny shop and they took it out and drove it right away. I would get someone from a trans shop to drive it and see what they say.

Yeah I have the same problem in my '92 5.2. This isn't a tranny problem. If you guys are having the same issue, it's in the engine somewhere because if ou pay attention you can hear the hesitation in the exhaust and if you hold it at that problem RPM it may continue until it backfires. Here's my list of things I've tried and any results they yielded.
prob: hesitation between 2k-2300 especially around 70-80mph.
Tried:
replaced pcv (no help)
replaced and indexed plugs and wires (problem changed to 2100-2500)
replaced egr (no help)
replaced cap and rotor (no help)
ran FI cleaner (no help)
replaced fuel filter (no help)
I'm thinking that indexing the distributor cap may relieve this. If anyone tries it before I do let me know. Thanks

could be a bad bushing in the dist. drive in the engine. They cause a surge or buck when they wear out.

had the same problem on my 92 5.2,finally found dodge tsb 181692a. tsb calls for reindexing distributor/timing.you can find this info on dodgeraminfo.com. beleive me it worked,truck now runs fine. my truck did not have the same timing marks called for in bulliten,so I used 10 degrees advance(factory setting per hood sticker).vehicle vacuum also increased resulting in better brake pedal feel,nice bonus! sincerely hope this helps someone!

Caution to all Dodge Dakota V8 5.2L owners. I know several people including myself that have the same problem (while foot off gas and coasting, then you hit the gas the vehicle hesitates and then bucks to get going almost like it's not catching). Mine has been at the shop (Carter Dodge) in Connecticut for 6 days now and although they can reporduce the problem they have no idea how to fix it. It's like they either don't care or they can't. This is my last Dodge ever!

I work at a local shop in Duluth, MN we've had 2 daks with the same problem and all we did was index the dist. like several ppl here said. You can monitor it via a computer but mine has the same problem so I checked it with the computer and it's within its proper parameters and still does it... so I don't really know what to say. Mine does it more so off a cold start at low rpms under load.

SUBJECT:
Surging, Bucking, Or Intermittent Missing
THIS BULLETIN SUPERSEDES TECHNICAL SERVICE
BULLETIN 18-16-92 WHICH SHOULD BE REMOVED FROM
YOUR FILES. REVISIONS ARE HIGHLIGHTED WITH
**ASTERISKS**.
**THIS BULLETIN APPLIES TO 1992 VEHICLES EQUIPPED
WITH 3.9L OR 5.2L MPI ENGINES AND 1993 VEHICLES
EQUIPPED WITH 3.9L, 5.2L OR 5.9L MPI ENGINES.**
MODELS:
1992--1993**
(AB) Ram Van/Wagon
(AD) Ram Pickup/Ramcharger
(AN) Dakota
**1993**
(ZJ) Grand Cherokee
SYMPTOM/CONDITION:
Vehicles may exhibit surging, light bucking, or
intermittent engine misfiring. This will most
likely occur when the vehicle is at operating
temperature, and under a light load at
approximately 2000 RPM. This condition may be
caused by a mis-indexed distributor. The following
procedure is an alternative to the indexing
procedure outlined in the service manual.
REPAIR PROCEDURE:
This bulletin outlines an alternative distributor
indexing procedure.
1. Connect a voltmeter to the distributor
sensor connector by removing the end seal and
carefully back probing the connector. Connect the
positive lead to the sensor output pin (pin 3,
either a tan wire with a yellow tracer or a gray
wire, depending on vehicle application). Connect
the negative lead to the sensor ground pin (pin 2,
a black wire with a light blue tracer).
2. Rotate the engine clockwise as viewed from
the front, until the number one piston is at Top
Dead Center (TDC) of the compression stroke. The
timing mark on the vibration damper should line up
with the zero degree (TDC) mark on the timing
chain case cover.
3. Continue to rotate the engine slowly
clockwise until the V6 or V8 mark (depending on
engine type) lines up with the zero degree (TDC)
mark on the timing chain case cover. The V8 mark
is 17.5°after TDC and the V6 mark is 147°after
TDC.
NOTE:
DO NOT ROTATE THE ENGINE COUNTER CLOCKWISE. IF THE
ENGINE IS ROTATED BEYOND THE MARK, RETURN TO STEP
2 AND REPEAT THE PROCEDURE.
4. Loosen the distributor clamp bolt.
5. With the ignition switch in the ON
position, rotate the distributor slightly in
either direction until the voltmeter switches
between the sensor transition point of 0 and 5
volts.
6. Adjust the distributor as close as
possible to either side of this transition point
and tighten the distributor clamp bolt to 170-230
in.lbs. (19-26 N-m).
