Hi I picked up a 2002 a ford excursion with a misfire computer says ignition coil so I did that replaced all 8 and plugs sill still has misfire engine has 117.000 miles on it and put a fuel filter


misfires are also from problem injectors and low fuel pressure
the code would have stated which cylinder was misfiring to identify the injector at fault
read the codes again and post the code found

Need fuse box and semantics for 99 Lincoln Continental it has code 301 & 308 stalls when you put it in drive.


What do you need fuse box an wiring diagrams for ? P0301 an P0308 are misfire codes . Has nothing to do with fuse , spark plugs ,spark plug wires etc....
P0301 through P0310 - Misfire Detection Monitor The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or any other cause.
  • Ignition system
  • Fuel injectors
  • Running out of fuel
  • EVAP canister purge valve
  • Fuel pressure
  • Evaporative emission system
  • Base engine
The MIL will blink once per second when a misfire is detected severe enough to cause catalyst damage. If the MIL is on steady state, due to a misfire, this will indicate the threshold for emissions was exceeded and cause the vehicle to fail an inspection and maintenance tailpipe test.

2009 chrysler sebring changed spark plugs cause it said number 3 was misfireing them put in a new thermostat in it started up but then started back not wanting to crank it acts like its flooding


were you sure to set the gap on the plugs? and replace them with the correct plug for that matter? also...why was the thermostat replaced?

Service engine soon light flashing


that usually means that you have an engine misfire bad enough to damage your catalytic converter. Have your engine codes pulled to identify which cylinder or cylinders are misfiring. What engine do you have?

Do you have problem with misfire.Could be coils.

2003 Sebring lxi coupe Multiple misfire with new distributor new crankshaft sensor new plugs and wires


Hi Aka, Vehicles fitted with distributors do not usually have crank or camshaft sensors. As yours is indicating multiple misfire I believe it does not have a distributor bot instead either individual coils or twin coils per two cylinders. Have a diagnostic scan carried out and that will identify which cylinders have had or are still having a problem. It is sometimes required on some vehicles to delete the fault codes before the vehicle will run correctly. All that an be done during the scan. If there are other problems they will also be identified. Regards John

What does acam or crankshaft sensor do


  • The crankshaft position sensor identifies position of the crankshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM)
  • When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown.
  • The camshaft position sensor identifies position of the camshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM)
  • When not replaced, vehicle could experience no- or hard start, long crank time, misfire, lack of power, excessive hydrocarbons in oil, spark plug fouling, catalytic converter failure, poor fuel economy, CEL/MIL illumination or intermittent shutdown

    Ford code 316


    Hi,

    Are you are referring to Fault Code P0316?

    If yes, then P0316 = Misfire Detected On Startup (First 1000 Revolutions)

    This is a generic code for all vehicle makes and as this code has not identified a particular ignition circuit, further diagnostic analysis will be required to determine the cause of the initial misfire.

    If this misfire condition does not re-occur, your OBD computer will eventually erase this code.


    Hope this helps.......

    I have a 02 ford mustang and it is misfiring more then one piston is misfiring i have changed celoniod, top engine cleaner , cleaned intake, checked the catalytic converter, changed plug wires


    Go to Autozone or Oreillys and get a FREE scan. This scan will identify the cylinder that is misfiring. Your model may have a Crank and Cam sensor that is failing. These components replace Distributors in function.

    A scanner should identify the problem.

    Looking for cylinder diagram/location on 2001 Ford Escape 6 cyl


    here's the scoop. There is a TSB that addresses this issue.
    First, replace the spark plugs.
    Next, replace all 6 COPS, coil on plug. You have to because they feed back into the PCM, Powertrain Control Module and blow the drivers. Then you need to replace the PCM.

    This was for 2004-06, but it might apply to yours if it's a 3.0L.

    Misfire DTC codes identify which cylinder is misfiring.

    Misfire Detection Monitor The Misfire Detection Monitor is an on-board strategy designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or any other cause. The Misfire Detection Monitor will be enabled only when certain base engine conditions are first satisfied. Input from the ECT or CHT, MAF and CKP sensors is required to enable the monitor. The Misfire Detection Monitor is also performed during on demand self-test.
    1. The PCM synchronized ignition spark is based on information received from the CKP sensor. The CKP signal generated is also the main input used in determining cylinder misfire.
    1. The input signal generated by the CKP sensor is derived by sensing the passage of teeth from the crankshaft position wheel mounted on the end of the crankshaft.
    1. The input signal to the PCM is then used to calculate the time between CKP edges and also crankshaft rotational velocity and acceleration. By comparing the accelerations of each cylinder event, the power loss of each cylinder is determined. When the power loss of a particular cylinder is sufficiently less than a calibrated value and other criteria is met, then the suspect cylinder is determined to have misfired.
    1. Misfire type A:

      Upon detection of a Misfire type A (200 revolutions) which would cause catalyst damage, the MIL will blink once per second during the actual misfire, and a DTC will be stored.

      Misfire type B:

      Upon detection of a Misfire type B (1000 revolutions) which will exceed the emissions threshold or cause a vehicle to fail an inspection and maintenance tailpipe emissions test, the MIL will illuminate and a DTC will be stored.

      The DTC associated with multiple cylinder misfire for a Type A or Type B misfire is DTC P0300.

      The DTCs associated with an individual cylinder misfire for a Type A or Type B misfire are DTCs P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, P0309 and P0310.
