SOURCE: P0302 code on 2003 Mountaineer. rough idle lose power during cellaration

You are having a misfire on your number 2 cylinder.  The first thing that you want to check is your spark plug and the wire that connect it to make sure the connection is good.  Check the plug to make sure that it is not fouled.  If both of those seem to be good I would next check the ignition coil pack to see if it is bad.  Another possible cause could be a faulty PCM or the wiring that runs from the PCM to ignition coil pack.  The only way to accurately trouble shoot the problem is with an oscilliscope and a diagnostic scanner.  Without these you have to kinda start at the top of the list and work your way down.  I would start with the plugs and let me know as you work your way down the list and we can help you on your way.  Good luck and thanks for letting me help you with your vehicle maintenance.  Thanks for an honest rating.  Please continue to use FixYa for future car troubles and let others know about the services available here!

If you have the check engine light on, rent a scanner, read out the code(s), and pursue to repairs. Possible problems are: idle air valve, vacuum leak (hoses and loose bolts) on intake manifold, EGR valve defective or not properly controlled, PCV valve defective, sticky injectors, bad plugs/wiring, O2 sensor, ect.. Use the scan codes to replace parts--don't just start swapping parts till it works.

Hi, if your EGR valve is stuck open, it could cause a rough idle. P1400 indicates there is a problem with the EGR flowmeter. This may be the result of a valve that is stuck open or may be the cause or may be unrelated. What I recommend is to first check the vacuum hoses on the sensor/flowmeter and also check the hoses from the EGR solenoid to the EGR valve and from the intake manifold to the solenoid. If those are good, remove the EGR valve and inspect the EGR passages for blockage. Also check the valve for properoperation. The valve should default closed and open when engine vacuum is applied to the vacuum port. If you cannot find anything wrong, with the valve or passages, test the control solenoid that supplies vacuum to the EGR valve. It should click open when you apply 12 volts to it. If all this is good, check the wiring from the flowmeter to the computer for continuity. Please let me know if you have questions, and thanks for using FixYa.

This car you are driving is 20 years old. Have you thought of getting a newer model? It sounds like you are having too many problems.
