Question about 1995 Ford Explorer

1 Answer

Rough start I have owned my 1995 Explorer for seven years and almost since then it will start rough when hot and as long as you throw it into gear fast it will keep running. I had it checked out but was told they couldn't find anything. I now have 190k miles on it and am considering replaceing it, I would keep it if I could get this problem resolved. Except for this issue it has been trouble free.

Your problem is more than likely a vacuum leak at your upper and lower intake manifolds. have the workshop check your long and short term fuel trim if it is above 3.5 ms then you can be sure it is a vacuum leak.

Rough idle, and will not go into 1st or 2nd gear


The first and second gear thing sounds like the pressure plate is worn or maybe the throw-out bearing is shot. The rough idle could be from a bad spark plug, bad plug wire or maybe something worse (clogged injector, fuel filter).

4.0 liter v 6 idles very rough


Rough idle is usually a symptom of a vacuum leak especially if the engine runs good at full acceleration. You have 14 year old vehicle, so check all under hood vacuum hoses.

Changed water pump and timing belt today and now the car is rough starting like its the starter or fuel something


You most likely threw the timing off when you changed the timing belt.. Even throwing the timing off 1 tooth can cause it to run very rough.. I would check the timing marks on the belt and make sure they align with the marks on the timing gears. Good luck

Starts good but bogs out in gear


Tuned-up lately, like new plugs & wires? Check EGR Valve, and also cycle key to retrieve any trouble codes that may be stored that will point you /us in right direction, and let us know what came up. Turn key to on, off,on,off,on, and leave in on position & count flashes of "check engine" light. goes like this: 2 flashes, pause, 2 more is code 22. 3 flashes,pause 4 more, is code 34........write them down & get back.

Running rough and wants to die


Have the fuel pressure at the fuel rail checked. If you just want to throw parts at it: Fuel filter by the tank first. Fuel pressure regulator next. Order of ascending expense and likely hood. Does the fuel pump hum louder lately? The fuel pump may be on it's way out. It's not getting enough fuel to do anything but idle. Why that is takes some investigation. Somebody like Auto Zone may check your fuel pressure. If the fuel pressure is good, bad spark plug wires are the next guess. Lift the hood and run the engine in the dark (take the light bulb under the hood out if it still works to do this) If you see little lightening bolts traveling over the engine you need new plug wires. If the fuel pressure is good, the wires are good, change the spark plugs. Good Luck!

1995 eagle talon esi none turbo


sounds like you may have an injector seal leak or an air leak at the filter check all fittings the rough idle is not abnormal with the air but a tune up will help also there is an air control solenoid if you left it unhooked broke a wire to it it will not start with the pedal being pushed and will idle lower than normal and very rough when air is on that is what i would at first..

Rough idle at start up


This is common and there is likely nothing to fix. It gets worse as the oil gets dirtier.
