generally, when the engine is washed, water gets trapped behind the spark unit and stays there, creating a shorting path for spark plug current. best to dis-mount the spark unit (follow plug wires back to source) and dry and clean it thoroughly.

Often, on the Escorts of this vintage, rough idle can be due to a leak in the vacuum system. With the engine running, listen closely for any tell-tale hissing sounds coming from any of the vacuum hoses. Check that they are all securely in place and the end-clamps are all tight. Also check that the PCV valve and the hose connecting it to the manifold are securely in place. Another possibility is the Idle Air Control (IAC) valve. If it is clogged or sticking, it can cause rough idle. Refer to a service manual to diagnose the IAC valve. Other things to check: make sure that the air intake is unobstructed and clean. You might consider cleaning the manifold and throttle body. Check the air filter and replace if necessary. Let me know if you have any other questions.

I had a coil pack that I just change less than seven days prior burn up then I change out but not it will crank but not start im stumped it is a Mitsubishi endeavor 2004 6cyl.


Hello,

Assuming your spark plug firing order is correct after the coil pack replacement and your plugs and plug wires are clean and connected properly--and you have gas in the vehicle--I am thinking Throttle Position Sensor (TPS).
To test the TPS you hold the throttle pedal to the floor and start the vehicle, if the vehicle starts you need to clean or replace the TPS.

If the vehicle will still not start and everything was replaced on the vehicle as the parts came off of the vehicle--and the vehicle ran before think:
Compression: Washed cylinders (pull plugs and squirt clean oil in spark plug holes (one-two squirts).
Fuel: pull hose after fuel filter and crank vehicle
Spark: Pull plug wire and arc with screw driver when cranking engine. New coil pack could be faulty.

You may need someone to crank the vehicle (mind your hands) while you test. You should be able to find videos for spark testing.

I hope this helps.

depending on how you pulled the plug leads off the plugs will result on wether or not you have damaged the leads. It is very easy to separate the wire end from the carbon track inside the lead and so they will misfire.. Suggest you get new plug leads and be careful on how you handle the leads when pulling them off the plugs.

My 02 galant runs rough when put in gear but in idle runs okay it also surges up and down replaced the plug wires


Okay, lets start with the oil you found on spark plugs when you were replacing them. this oil is coming from the valve cover tube hole area, notice the plugs go into the holes in the valve cover, there is a gasket the goes around the top of the tubes and when it leaks it goes into spark plug hole, the valve cover needs replacing .
this will cause rough idle and running problems, after replacing valve cover gasket the holes must be cleaned, using crab cleaner, spray into holes and use air to blow out . this may need to be done a few times to get oil out .
after oil is removed . then remove spark plugs and wipe them clean.
The next step is to find the air (vacuum leak) , you said you hear it around intake tube. check for cracks or broken vacuum line. this leak will cause idle problems and driving problems,

My car idles really high and drives on its own up to 40 miles an hour. I changed the tps; the spark plugs; the valve gasket cover cause oil leaked out into spark plugs and new plug wires changed the fuse...


Sounds like the AIC...Air Idle Control is stuck...usually located on the plenum just past the air intake hose/line...you can try cleaning the AIC before replacing it...Hope this helps.

Pull the spark plug wires out one by one and check for oil on wire. Sometimes the valve cover spark plug hole gaskets leak oil into the spark plug hole and causes a misfire. If oil found clean with brake or carb cleaner and blow out with compressed air. also when car runs bad listen under hood for snapping noise this would be spark escaping to ground somewere. In a dark garage you might be able to see the spark.
