Run injector cleaner in the fuel
clean the faulty injector tip
misfires are more from injector and dirty fuel problems than coils and plugs

SOURCE: Check engine light

A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.

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 wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the 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.

Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.

Sounds like it is the EVAP and I think there is a TSB on this that the dealership should fix for you.

From a reputable repair website:


P0351 - OBD-II Trouble Code

Auto Systems and Repair

Ignition Coil "A" Circuit Primary/Secondary Malfunction Our emissions expert has put together the following information about the P0351 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
OBD II Fault Code
  • OBD II P0351 Ignition Coil "A" Circuit Primary/Secondary Malfunction
What does this mean? The ignition coil or coils are responsible for igniting the air/fuel mixture inside the combustion chambers. Without reliable performance from the ignition coil(s) the vehicle will stumble and misfire.
Code P0351 indicates there's an electrical problem in either the primary ( the computer side ) or the secondary ( the spark plug side ) of the Ignition Coil "A" Circuit.
Symptoms
  • Check Engine Light will illuminate
  • Engine idles rough
  • Engine misfires on acceleration
  • In rare cases, the engine may not exhibit noticeable symptoms
Common Problems That Trigger the P0351 Code
  • Defective Ignition Coil(s)
  • Defective Spark Plug(s)
  • Intake Manifold Vacuum leaks
  • Carbon buildup in the Throttle Body air passages
  • Defective Idle Air Control Valve or Electronic Body
Common Misdiagnosis
  • Ignition coil(s) replaced when cause of the malfunction was a vacuum leak
  • Spark Plugs replaced when cause of the malfunction was a vacuum leak

Initial start up the engine sounds like its running on 2 cylinders under powered intil the temp gauge reads normal ???? any body got the answer please


Cold starting misfires can often be caused by either tired high tension spark plug leads or ignition coil packs. If replacing leads, then replace with a full, new set. Coils can be changed individually, but it is often the case that if one has failed, then the others aren't far behind. Some cars have individual coil packs on each spark plug. Some cars have a single pack for all plugs and some have coil packs which may control two or more plugs.

To check for a misfire (ignition failure) follow these steps:

(Cold start) (Use a pair of insulated pliers)

1) Start the vehicle

2) When the vehicle starts misfiring, disconnect plug leads or coil pack connections one at a time. If the vehicle idles even more roughly, then that plug or pack should be considered fine.
Replug each connection before disconnecting the next one. Once you disconnect a plug lead or coil pack connection and find no difference in poor engine running, then you have likely found the offending cylinder. Check the spark plug condition, lead and/or coil condition and connections on that cylinder.

3) Replace components as necessary.

Truck dies when idling


HI
first I would like to tell you, do this procedure only if the 5th digit of your VIN is C or K.

Description

The engine control module (ECM) learns the idle position of the throttle plate to ensure the correct idle. Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position. The idle may be unstable or a DTC may set if the throttle position is not learned.

Conditions for Running the Throttle Learn Procedure

• DTCs P0101, P0102, P0103, P0107, P0108, P0111, P0112, P0113, P0506, and P0507 are not set.

• The engine speed is between 450-4,000 RPM.

• The manifold absolute pressure (MAP) is greater than 5 kPa.

• The mass air flow (MAF) is greater than 2 g/s.

• The ignition 1 voltage is greater than 10 volts.

Throttle Learn

Important: Do NOT perform this procedure if DTCs are set. Refer to Diagnostic Trouble Code

(DTC) List - Vehicle.

1. Start and idle the engine in PARK for 3 minutes.

2. With a scan tool, monitor desired and actual RPM.

3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease.

4. Ignition OFF for 60 seconds.

5. Start and idle the engine in PARK for 3 minutes.

6. After the 3 minute run time the engine should be idling normal.

Important: During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn.

* If the engine idle speed has not been learned the vehicle will need to be driven at

speeds above 70 km/h (44 mph) with several decelerations and extended idles.

7. After the drive cycle, the engine should be idling normally.

* If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds

and repeat step 6.
8. Once the engine speed has returned to normal, clear DTCs.
Good Luck

What engine size ? Did you check for vacuum leaks at the intake manifold . How many mile's on the engine ? Oil in cylinders ? weak piston rings , what kind of compression reading's ? Do .compression testing .Have it hooked up to a factory or professional scan tool to check engine sensor data . Unless you like just replacing parts and making part stores rich . Your vehicle also has electronic fuel control , fuel pump driver module ! There is a fuel pressure sensor on the fuel injector fuel rail ! Tell's the PCM how much pressure ! 39 psi is good engine off or idling .

Ford Electronic Returnless Fuel System Diagnosis Part 2

Fuel Pump Driver Module Applications
The fuel pump driver module (FPDM) communicates diagnostic information to the powertrain control module (PCM) through the Fuel Pump Monitor (FPM) circuit. This information is sent by the FPDM as a duty cycle signal. The three duty cycle signals that may be sent are listed in the following table.

My ford windstar 2003 hesitates during cold weather or wet conditions. But good during idle. Some time shows blinking engine light.


The flashing and rough running is to to a misfire or misfires cause by arcing due to moisture on ignition components. Eventually these misfires can lead to other problems such as damage catalytic converter. Start by identifying which cylinder(s) is/are misfiring. The arching can be reproduced with a spray bottle filled with soapy water. Spray the ignition components (wires, coils, distributor cap...)and look for the vehicle to idle rough. Replace any faulty component.

I have a 99 mercury villager, getting a 0340 code. it says its for a crankshaft sensor but vehicle doesn't have one. What does this code mean?


Hi, code 340 is for the camshaft sensor. Below is a test you can run to check the sensor. The PCM is above the glovebox. Do not disconnect or remove the PCM. Just remove the glove box and probe the back of the connector to access the pins indicated in the cam sensor test. Please let me know if you have any questions, and thanks for using FixYa.

1999-00 Vehicles

On 1999-00 vehicles, the camshaft position sensor must be checked with the engine running. If a no start condition is encountered, observe the MIL. With the ignition switch on and the engine off, the MIL should be illuminated. If the camshaft position sensor is functioning, the MIL should go out when cranking the engine.
  1. Run the engine until it reaches normal operating temperature. Leave the engine running.
  2. Using a voltmeter set to the DC range, connect the negative lead of a voltmeter lead to the negative battery terminal or chassis ground.
  3. Connect the positive voltmeter lead to the back of the PCM electrical connector in terminal 44.
PCM pinout

jturcotte_1222.gif

  1. Observe the voltmeter reading. The reading should be 0.3-0.5 volts.
  2. Disconnect the positive voltmeter lead from terminal 44, and connect it to terminal 49.
  3. Observe the voltmeter reading. The reading should be approximately 2.5 volts.
  4. Perform steps 3 through 6 with the engine at 2,000 rpm with the transaxle in park. The voltage readings should be the same.
  5. If the observed voltages are not within specifications, the sensor may be faulty.

REMOVAL & INSTALLATION
The camshaft position sensor is part of the distributor assembly, and must be replaced as a unit. Please refer to Engine Electrical, Distributor Ignition System, Distributor, Removal and Installation for the procedure.

Chances are you have an oxygen sensor problem. When the engine warms up, the engine computer moves from open loop operation to closed loop, and it then uses the O2 sensor readings to adjust the fuel. If the sensor(s) is contaminated, it will send a false reading to the computer causing this problem.

First, is the check engine light on? If so, have the codes read at Autozone for free if you do not have access to a code reader. Furthermore, If not, then precede as follow, change your Idle Air Control (IAC) and if you have not replaced you cables then I would suggest that as well. If your vehicle is equipped with coils then you should receive a misfire message on the diagnostic tool/scanner. But given the age of your vehicle I would change the coils as well.

Bottom line, if your check engine light is on, have the vehicle analyzed with a scanner. If your vehicle is registering no code or no light malfunction then I would precede with changing the IAC, if equipped and the cables.

Good Luck
