Pull the coil from the plug, Remove the spark plug and inspect for any moisture in the plug hole. If you see a black line down the side of the plug. Called carbon tracking, replace the plug. To see if coil is firing move it to another hole and restart. ford's misfire monitors are fun to set. Takes up to 45 minutes to get them to pick up under specific conditions. Good Luck.

SOURCE: engine code p0307 cylinder #7 misfire

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

SOURCE: #7 cylinder misfire dtc p0307

Best place to start would be with spark plug and have a look at it. Wet with fuel would indicate no spark, carbon build up, bad wire or plug etc. If your familiar with testing at spark plug to confirm spark getting to plug, then do that first. If no spark to plug, coil pack would be next, or distributor parts such as cap, wires, rotor etc. If getting spark, then try cleaning and checking connections to injector. There are other more expensive things that may be causing it, but lets try the cheapest, most common and easiest first to narrow it down, and get back to me/us, if still having problem.

A code P0307 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

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.

Ford's will sometimes flag the wrong cylinders on misfires. Usually a coil will fix Ford's misfire. Spark tester to me just verifies that the the circuit is good. Dont relay on this to say the coil is ok.

Keep us updated.

2006 grand prix gxp 5.3. When you are driving normally it will miss from 50mph and up. When you punch it it doesn't miss a beat. I cleaned the maf sensor and air filter, Plugs were replaced.


It's probably a coil breaking down , have a scan tool hooked up an have misfires checked to see which cylinder is missing .
Ignition Coils
Each ignition coil has an ignition 1 voltage feed and a ground. The engine control module (ECM) supplies a low reference and an ignition control (IC) circuit. Each ignition coil contains a solid state driver module. The ECM will command the IC circuit ON, this allows the current to flow through the primary coil windings for the appropriate time or dwell. When the ECM commands the IC circuit OFF, this will interrupt current flow through the primary coil windings. The magnetic field created by the primary coil windings will collapse across the secondary coil windings, which induces a high voltage across the spark plug electrodes. The coils are current limited to prevent overloading if the IC current is held high too long. The spark plugs are connected to their respective coils by a short secondary wire. The spark plugs are tipped with iridium for long life and efficiency.
Drive it long enough like that (with it misfiring ) the check engine light will flash . This is to warn that a catalytic converter damaging event is taking place . This would also set a DTC - diagnostic trouble code

I have an 2005 ford f250 with the 5.4L. and its showing codes po174, po300, po305, po307 and i alreadt put a new maf in. what should it look at next?


Did you resolve the other codes? p0300 random multiple misfire, p0305 misfire cyl #5, p0307 misfire cyl #7? You could have bad ignition coils or a vacuum leak. Check your coils and check for vacuum leaks at the intake manifold check vacuum hoses. Hope this helps!

Codes. 0307. O128. 0316. 1000. 2106.


P0307 = cylinder no.7 misfire detected.
P0316 = misfire detected during startup-first 1000 revolutions.
P0128 = coolant thermostat (coolant temperature below thermostat regulating temperature)
P1000 = On board diagnostic readiness test not complete.
P2106 = Throttle actuator control (TAC) system----forced limited power mode.

Check the spark plug, spark plug wire, coil, and fuel injector for cylinder 7. Check compression on cylinder 7. When the no. 7 misfire is solved, clear the codes.
