Catalytic converters on the Dakota's were a recall issue from 1999-2003 models.
I had a 99 and a 2001 and had the same problem on both.(3 times on the 99 and once on the 01)
You should also check the speed sensor on the rear axle.
The neutral safety switch and the EGR valve.

If I were you,I would start with the Cat and EGR,then check the other stuff if you still have issues.

Missing,viborating


Misfire could be a number of things:
a) spark plugs - change them if used over 15K miles - inspect/regap.
b) spark plug wires - change them if over 15K miles - inspect
c) ECM (electronic control module) - test with HEI (high energy ignition) tester.

The vibrating tells me that the engine is running on less than its normal compliment of cylinders - the shaking is produced by the imbalance caused in the engine by one (or more) cylinder(s)
not firing at all.

The "Check Engine" light probably is coming on due the the misfire condition. Go to Pep Boys or
Advance Auto Pats, where they'll tell you (free) your codes causing the "Check Engine' light to be
lit - the code coming from your truck's computer will probably be one or more of:
P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel

What is the meaning of 98 Honda Civic error codes P0300 P0303 P0304? Engine will not start, does not seem to fire.


P0300 indicates that there is multiple miss fire in the ignition system. P0303 and p0304 indicates the miss fire is in cylinder #3 and #4. Replace the spark plug, and wire set, and rotor and cap if there is one. Can not remember if there are coil packs on the civic, the age thing. change the fuel filter and clean out the fuel injectors with fuel injector cleaner for the next 3 full ups. When the spark plugs are removed, inspect them for condition, if there clean or dirty with carbon build up. which would indicate how the engine is running. Keep me posted and drive safe.
