    The overheating started first then weeks later it started running very rough

  • Anonymous Jan 22, 2013

    You don't use a vehicle that overheats,you will cause more damage. Of coarse it runs rough,you kept using it instead of diagnosing & resolving the issues

  • Kim Jordan Jan 22, 2013

    Look smart *** I didn't keep using the car keep do things to hopefully solve the issue like thermostat , water pump and flush the system

  • Kim Jordan Jan 22, 2013

    It has not been driven since it started overheating it has been started long enough to see if problem was solved and then cut off immediately when temp started rising

To be misfiring on all cylinders on one side &
also overheating,I would be checking into a
possible head gasket failure.

You stop using any ford with a flashing mil lamp
on dash or constant misfire code present, or you
ruin first the exhaust converters, then maybe whatever
your current issues are

SOURCE: how to fix misfire cylinder # 6

DTC P0306 - Cylinder #6 Misfire Detected
A P0306 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 #6.

Symptoms may include:

the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present


A code P0306 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer


About 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.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

2004 trailblazer code po306 and we changed out plugs, coil and still po306


Diagnostic Test Code (DTC) P0306 is defined by SAE J2012 (REV, DEC 2007) as "Cylinder 6 Misfire Detected".

To put it plain and simple, there is a problem with cylinder #6 in your engine that is causing it to misfire.

Misfires can be caused by several things. One of the things that must be understood is that a misfire is simply one or more cylinders that are not producing the power that they should. - especially when compared to other cylinders in the same engine.
The things that can cause this include, but are not limited to:
> Ignition system
> Fuel delivery system
> Fuel injection system
> Cylinder compression (which can be affected by many of the things below)
> blown head gasket
> Burned or bent valves
> Vacuum leaks
> Faulty wiring
> cracked piston or broken piston rings
> Restricted exhaust
> malfunctioning Powertrain/Engine Control Module (PCM or ECM)


To fix the code, you must first diagnose to determine which of these things is causing the misfire, then repair accordingly.

I would go with the ones autozone gave to you.then I would check the coil packs for those 2 cylinders and see if that's the problem. If that ain't the problem then I would check the crank sensor

After going over 40mph the check engine light goes on n it gives the code 440


How did you read that code on your car? A 92 Accord is supposed to give you pre-OBD honda codes, which are all below 100. Please check the code again and re-post it.

2002 ford escape 3.0L DTC P0305and P0306 what would you ck


P0305 - Cylinder 5 Misfire Detected
P0306 - Cylinder 6 Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, The Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

Possible Causes:
- Improper spark plug at cylinder #5 and #6
- Insufficient compression at cylinder #5 and #6
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #5 and #6
- Fuel injector #5 and #6 may be faulty
- Intake air leak at cyli

Possible Solution:
- Perform Injector Service
- Replaced Spark Plug #5 and #6
- Replaced Injector #5 and #6
- Replaced Ignition Coil #5 and #6

Hope helps.

1999 jeep cherokee 6 cylinder engine light


1.Plugs
2. Vacuum leak
3. Injector fault
4. High or low fuel pressure.
Thats the list of things to check.
This is a #3 cylinder misfire.
There is also TSB about #3 injector needing added heat protection. This could definitely be the cause. I start at plugs and go from there.
Hope this helps.
Thank you,
Lee
