Random can mean across all cylinders or it can mean intermittent on one cylinder. Remove each spark plug in turn and inspect it taking note of gap and colour. With the fuel pump relay and fuse disconnected check on the quality of spark generated at each plug. If one or two plugs look different or weak spark this will direct you to either a faulty coil set or renewal of plugs. Now inspect the spark plug high tension connector lead and check for burnt signs of tracking or shorting through it to the cylinder head. If everything is OK change your crank sensor. If fault persists change the cam sensor.

I have a 2000 Dodge Stratus with a random misfire on 1,3 and 5. The engine runs fine besides a twitch in the motor that can be felt while idling. Already replaced plugs and wires. Suggestions?


get the OBD codes read this will tell you which switch/sensor is causing the issue , the last random misfire i encountered turned out to be low cylinder compression so if the OBD code says " random misfire " then get the cylinder compressions read , hope this helps

Tip

Dodge Durango Won't Start, Turns over, NO BUS on instrument cluster


1998 - 1999 Dodge Durango 3.9L
2000 - 2001 Dodge Durango 4.7L
1998 - 2000 Dodge Durango 5.2L
1998 - 2001 Dodge Durango 5.9L

The PCM has 3 connectors plugged into it. Try wiggling each connector and listen for a clicking sound, starting with the connector furthest from the front of the Durango, and the middle connector with a white top.

If this doesn't help, replace your PCM. The PCM (power control module) can get hot, causing a short or broken circuit inside the module. Replacing the module will fix the problem. If your truck dies randomly when it's hot outside, but will start back up after it cools down, this is probably the problem.

Same cylinder all the time? What brand of spark plug did you put in? Have you cleaned injector connection? If spark plug and wires are known good, injector and connection would be next. Did you erase code after other work done?

P0300 is a Random Misfire
P0302 #2 Cylinder Misfire
U1120 The code U1120 means, lost wheel distance message. The powertrain control module(PCM) is not
receiving a signal from the anti-lock brake module. The problem could be a short in the bus circuit,
the PCM or the anti-lock brake module. This type of problem is best diagnosed by the dealer or a
local shop with the proper diagnostic scanning equipment. Hope this helps.

The p0300 What does that mean? Basically this means that the the car's computer has detected that not all of the engien's cylinders are firing properly.
A P0300 OBD DTC code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-
==================================
The p0430 What does that mean? Basically this means that the O2
downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions
system.

2000 dodge durango misfiring


first replace the spark plugs, if still misfiring check compression if low the engine needs to come apart looking closely at the valves, if compresssion is EQUAL +- 10psi on all cylinders then injectors are suspect

2000 dodge durango misfire # 3 Cyl


This prob sounds like an engine intake valve is stuck open. This is usually caused by very high revs! Check the compression on this cylinder. Frankster016
