check to make sure #5 spark plug wire isn't bad,make sure you have not wired it wrong from changing plugs. You should purchase a chilton manual if you haven't already

have the crank sensor check for erratic operation. if you have done all of that then there is nothing else. and they way the computer knows it is misfiring (if it is) false code maybe and could be bad crank sensor. good luck

SOURCE: the code reads P 306 misfire on cylinder 6. How

A P0306 code means that 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

Causes

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

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.

I have a 2003 ford cv with a misfire on cylinder 6; THIS IS WHAT I change,new coil 5,6 new fuel injector 5,6 all 8 spark plug! Still the check engine light comes on .


code p 0306 refers to cylinder 6-- misfire detected ====causes --engine mechanical fault--wiring---ignition/fuel system--injector---ECT/MAF sensor---ECM
the mechanical fault can be
problem hydraulic lifter holding a valve partially open
loose valve seat insert
a compression test will determine if there is a mechanical problem as for the rest , check all connections for clean /tight terminals
substitute the ECM with a know good unit to eliminate it
substitute the ECT/MAF sensor with a known good unit
run the fault codes again as engine lights report on a variety of faults as well as the transmission faults

My 2006 ford fusion shakes or misfires around the speeds of 20 40 and 60 mph. I got all 6 coils changed the fuel injected cleaned and transmission oil changed. My engine light come on when it shakes...


I'm sorry to hear that. Did he tell you what codes were in it? Do you live near a autozone or somewhere they can check the codes for free. Or maybe you can call the person up and ask what codes are in the car. But it sounds like you are having a miss fire problem. If the check engine light is flashing it is not a good idea to drive it. Try to get the codes and post them please.

What is the firing order of 2006 3l bmw engine


Hi-

Number 6 cylinder is the cylinder closest to the firewall. For a misfire I recommend checking the coil and spark plug. The coils are known to fail.

Why does my vehicle stall when at idle.


Intermittin Engine Stall
Engine No Start
Missfire
MISFIRE IN motor cylinder is more likely the cause to engine stall and hard start.
You will have to fix this problem first,
A misfire, most the time, is caused by, incorrect cylinder firing order (diagram at bottom). Or no or low cylinder compression
no or low compression is the result of A Vacumm leak.
If the timing chain was recently replaced, the valve cover had to be removed, the valve cover gasket could cause a huge vacumm leak which would effect some if not all 6 cylinders,

Symptoms
Lack/loss of power
Hard start
Engine hesitation

For Now
check firing order( coil pack to sparkplug)
check sparkplugs

SPARK PLUG GAP 0.050''
SPARK PLUG TORQUE

My 2006 Ford Fusion seems to be experiencing an engine misfire. How do I find out the OBD code?


You well need a scanner, but even then Ford has some issues on miss fire detection in some vehicles, the ECM may need flashed to correct this problem.

If it works right it well point you to the right cylinder then you need to figure out if it's a plug, coil, boot over plug or some other problem.

What do I need done if codes p0171 p0174 p0301 p0305 p0316 is it major problems


OK, We'll cover the Diagnostic Test Codes (DTCs), starting with the standard definition set by SAE J2012 (Revised December 2007)
DTC P0171 "System Too Lean Bank 1"
DTC P0174 "System Too Lean Bank 2"
DTC P0301 "Cylinder 1 Misfire Detected"
DTC P0305 "Cylinder 5 Misfire Detected"
DTC P0316 "Engine Misfire Detected on Startup (First 1000 Revolutions)"

The "system lean" codes are pretty much telling you that there is way too much oxygen in the exhaust. There is too much oxygen on BOTH sides of the engine, and that is why you are getting codes for bank 1 and for bank 2. Bank 1 is the side where #1 cykinder is located and Bank 2 is the opposite side.

The misfire codes are pretty self-explanatory. #1 and # 5 cylinders are misfiring. The P0316 DTC is telling you that the misfire monitor is detecting a misfire as soon as the engine starts. This tells you that it is a very severe misfire and that the engine does not have to warm up and the car does not have to be driven to detect the misfire.

A misfire can be caused by many things it can be vacuum leaks, bad spark plugs, bad ignition cables, faulty ignition coils, fouled or malfunctioning injectors or injector circuits, blown head gasket, cracked cylinder head, burnt valves, etc.. etc..

However, look at the codes you have. Then look at the firing order for your engine. 2002 Mercury Sable is only equipped with a 3.0L 2V 6-cylinder engine.
The firing order is 1-4-2-5-3-6

Now if you take the firing order and split it in half, stack the two halves on top of each other, it looks like this:
1-4-2
5-3-6

When you look at the firing order this way, you can see that cylinders 1 an 5, 4 and 3, and 2 and 6, are "PAIRED" cylinders. They are exacly opposite in the firing order. Now, the cylinder only fires every second revolution of the crankshaft. With paired cylinders, one of the cylinders in the pair will fire on the first revolution and the other cylinder will fire on the second revolution.

Looking back at your codes, please note that the cylinders that are setting the misfire codes are paired cylinders.

Now the coil pack for your ignition is actually made up of three coils. Each coil fires a set of paired cylinders. If you look at the top of the coil, it will usually be marked with the cylinder numbers that each coil tower is supposed to connect to. The coil will look just like the firing order split and stacked as above.

With all of this said, I would say that it is VERY LIKELY that your misfire codes are being caused by a defective ignition coil.

The lean codes are a little different.

These are USUALLY caused by vacuum leaks which allow too much air into the engine that is not getting measured by the Mass Airflow (MAF) sensor and causes the engine to be getting too much air and not enough fuel (running lean).

I would take a good look at all of the vacuum hoses and lines. Ford is notorious for getting holes in the rubber parts that connect the PCV tubes.

If you do not find any obvious reasons for a vacuum leak, then you may want to fix the misfire codes, reset the computer memory, and drive the vehicle to see if the lean codes come back again. The misfires COULD be the cause of the lean codes. In a perfect world, this is not supposed to happen because the misfire monitors setting codes will not allow the oxygen sensor monitors to run and set lean codes. However, I HAVE seen cylinder misfires that have caused lean codes.

I hope this helps you to figure it out. Good luck!
