2000 dakota 4.7 v-8 codes p0300 p0303 p0304 p0307

Hi,

I hope I can help with this. This could mean the engine spark plugs or plug is the issue. Also check the exhaust pipe. White smoke indicates a coolant issue. Check your coolant reservoir. Black smoke indicates a Fuel issue. Blue is an oil issue. Also, speaking of your spark plugs there very well could be a misfire.

the code P303 could be cylinder 3 misfire
P102 the mass air flow sensor which is on the air filter cover. It's an electrical part and is sensor. Please check these and let me know.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/laura_08254539050d64db

next most common ,, intake manifold gasket

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.

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.
