    You may have a PCV hose that has deteriorated and is leaking vacuum, a very common problem on these vehicles. Which engine is it?

    There is a very common problem with the PCV hose underneath the intake plenum behind the throttle body, I will bet money that this is your problem. Which engine do you have?

There could be many things that can cause that. You many need just a simple tune up, such as new spark plugs, and wire set. The injector's may be getting dirty and the fuel filter may be at the end of it's life and needs to be changed.
If your going to tune it up your self, get the computer scanned at Auto Zone and see if there are any DTC codes that my be causing the problem. They scan for free and can give you the step by step instructions to any parts your going to replace such as the fuel filter and spark plugs.
For now if you like, try add fuel injector cleaner to your gas every time you fill up the gas tank to try to clean up the injectors. if things improve then just add it to the gas tank once a month. You can buy them at most gas stations but i find then to be cheaper at a parts store like Auto Zone or you can get them at Wal-Mart in multi packs to save you more money.
Good luck and hope this helps, a little preventive maintenance save a lot more then the repair at a later date.

Hi i have a 95 explorer and it will idle fine for awhile then it starts idling rough but if i hit the gas a few times alittle hard it will idle good again but after a minute it will idle rough again p


Check over your work--- you put the problem in it

Did you not make a diagram of the wires before you
removed them & mark the ends of the new ones?

Have to also know the firing order before you start
any job.

Did you gap the plugs correctly

2002 ford explorer sport trac , starts fine, runs good then about 30 min it starts to run rough,and idling poorly, not fuel or fuel filter


You need to check your plug wires for cracks and wear. The best way to know if they are bad is to run your engine at nightr and look for any time of blue arcing spark coming from any of the wires. I believe that replacing the wires will solve your problem.
