It could be a little bit of dirt got into the fuel system and got lodged and then cleared.Or it could be a bad injector on cyl #3.I would recommend that you change the gas filter and add some injector cleaner and run it through your fuel system and see what that does for your performance.Also you could give your car tune up because it could have a bad plug in that cylinder.Try these inexpensive fixes before jumping into any costly repairs.There are also service stations that can do a test on your injectors to be sure that there working properly.

Random multiple misfire P0300, P0302, P0304 on 2006 Kia Rio


A competent mechanic will check all probable causes associated with these DTC codes.
Code P0300: Random-Multiple misfire detected. Probable causes:
1. Vacuum leaks, damaged hoses, or improper routing
2. Fuel contamination
3. Ignition system - Ignition module, coil, spark plugs and wires
4. Fuel system
Code P0302: Cylinder 2 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system
Code 0304: Cylinder 4 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system

Be sure the invoice enumerates all of these probable causes as having been checked. Also, some of the replacement parts installed earlier may be faulty.

The engine light came on in my 2003 Honda civic LX. My mechanic stated code was misfiring on cylinder 3. He changed the coil pack and reset the engine light. The car still seems to misfire when it is...


If you pull the plug wire from the spark plug on cylinder 3, is there any oil, water, or antifreeze in there? Have you removed the plug to see what condition it is in? If it is black or oil-fouled, you should replace it, or better yet, the entire set of spark plugs. When the coil pack was replaced, was the plug wire replaced as well? I have seen a stuck fuel injector cause your problem before, because the cylinder does not get the right amount of fuel, running either too lean, or too rich.

I have a 2004 3.9L Mustang with the "check engine soon" light on. I read the codes and 0300, 0301, 0305 and 0316 were up, while the car was still driving fine. Soon, it started to lose strenght, I bar


Best to read the codes first---code p0300 refers to random multiple cyl-- misfire detected causes-- spark plugs---HT leads--ignition coils--wiring.
code p0301 refers tocylinder 1-- misfire detected causes ---engine mechanical fault---wiring---ignition /fuel system ---injector---ECT/Maf sensor(Mass air flow) ECM.
code p0305 refers to cylinder 5 misfire detected causes ---same as 0301
code p0316 refers to misfire detected during start up -first 1000 rpms---causes--- engine mechanical fault---wiring----ignition/fuel system---injector. I would run a fuel system pressure pressure test as the common causes here is the fuel/injectors

Up to this point in time, mechanic 1 has only done some maintenance work on the car. Things that would be done from time to time to maintain the car.
Since you have lost trust in this mechanic, I would go to a different place and have them diagnose the codes. If the second place gives you the same recommendation you can decide what to do.
You can tell the second place you are getting a second opinion, or not.

My 2001 Chevy Silverado just got a newly rebuilt ******. The day i got the truck back the check engine light came on. I took back to mechanic and he ran the code. It said misfire and that truck was running...


did the code set for multiple/random misfire or did it set for a particular cylinder or cylinders?if it is random or multiple misfire you may want to check the fuel pressure and volume and for a vacuum leak. if it is a particular cylinder or cylinders then check your coils and also the compression to make sure the engine rebuild is good and something didn't go wrong.

1999 Town Car began running very rough - suddenly.


When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.
