    With the newer cars the part that the coil pack plugs in to could be bad. This part is called the ignition control module. I don' know that this is the problem tho.



    Have you replaced the spark plugs and wires yet?



    Also what did you hve tested on the fuel injection?

If you just changed the coil pack by itself there is a good possibility that you may have had a bad spark plug or plug wire that contributed to the early demise of the coil. The plugs and wires are easy to change on this vehicle and should run you no more than $50-60 for the new plugs/wires and if you know someone or you want to do it yourself there should not be that much labor involved. For my Hyundai Accent that has almost 200k I use NGK plugs and NAPA Belden Maxx spark plug wires. This is the most likely cause of your continued problem. Hope this helps

Check the spark on cylindre 1 if its ok. that means your first cylindre timing valve or adjuster are not good.

Try spraying some brake clean where intake manifold meets cylinder head and see if engine rpm changes if so chances are the intake gasket is leaking.

After changing the coil pack and spark plug, why is it still skipping?


Timing could have jumped. Could be a bad head gasket also. even possible to be a small hole in piston check the cylinder for compression. Check the fuel injector to that cylinder if you have bad air to gas mixture it will throw a code of misfire change fuel filter check fuel injector to see if clogged. most likely it is the fuel injector .

2002 elantra cyl 2 random misfire


Hi there:A P0300 diagnostic 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-firing, nor why.

For example, a P0302 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #2; same condition in P0301 - cyl #1, P0303 - cyl #3 and P0304 - cyl #4.

A code P0300 (or 301, 302, 303 or 304) may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor
Defective computer

About your possible solutions, if there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.


Hope this helps.

I would start with the inlet manifold gasket, these are know to break down causing vacuum leaks which can cause this issue, also check around engine for other vacuum leaks

Diagnostic code p0301 idles rough after warming up, check engine lite is on, when accelerating check lite flashes and car bogs down letting up on gas helps engine catch up


P0301-

Trouble Code Conditions:
Engine runtime 3 seconds, engine speed change under 1200 rpm, and the PCM detected a misfire condition present in one cylinder during the 200 (Catalyst) or 1000 revolution (Emission) test range.Note: If the misfire is severe, the MIL will flash on/off on the 1st trip!

Possible Causes:

  • Fuel metering (fuel injector dirty) problem affecting Cylinder 1
  • Base engine (compression) problem affecting Cylinder 1
  • Ignition system (spark plug or plug wire) problem on Cylinder 1

My 1998 plymouth neon has a number 4 cylinder misfire. changed plugs, wires, coil pack. still misfires. does it at slow speeds and really bad when trying to get up to speed when entering the highway....


CHECK FUEL INJECTOR WIRING TO NUMBER 4 INJECTOR,HOOK A TEST LIGHT TO MAKE SURE IT BLINKS WHILE ENGINE RUNNING.THAT WAY YOU WILL KNOW IF PCM FIRING THE FUEL INJECTOR OR FAULT AT THE INJECTOR WIRING OR YOU HAVE INTAKE LEAK LOW COMPRESSION TO THAT CYLINDER BECAUSE OF BAD BURNED OUT VALVE.COMPRESSION TEST TO THAT CYLINDER CAN ALSO HELP.LOOK FOR LOOSE OR WORN DAMAGE ROCKER ARMS IF YOU HAVE A SOHC SINGLE OVER HEAD CAM ENGINE.

Trouble codes for saturn ls2 car is showing the following trouble codes. po300, po306, po451 p2bo3 and c112b


P0300 Multiple Cylinder Misfire Detected

P0306 Cylinder 6 Misfire Detected

P0451 EVAP Pressure Sensor Range/Performance

I have no idea what those last two are. Typo, maybe?

Your first two codes could be caused by old spark plugs and/or leaking plug wires.

Your EVAP code could be a bad fuel tank pressure sensor or a malfunctioning EVAP system. With that code, if you remove your fuel cap and get a whoosing sound, then it is an issue with your EVAP system not properly venting the tank. If you don't get that sound, then the tank pressure sensor is bad.

2000 elantra misfire code and slow


The first thing you should do is check the voltage to the coil. the voltage should be around 12 or 13. If their is then the coil could be bad. Buying new spark plugs and wires would not hurt. Try replaceing them first, then the coil.

Please let me know if your problems presist.

Thanks, Charlie
