SOURCE: 1998 Ford Explorer sport 4.0L 4x2 PCV Valve Location

the pcv is located on the rear(firewall) of the drivers side valve cover.turn counterclockwise and pull to remove be careful there are 2 small tabs inside the pcv hole in the valve cover(can feel with small finger) this is to hold valve in place so it wont leak.if you have a oil leak at the pcv a quick fix is to put a small amount of silicone around the pcv o-ring and install.wait hours for silicone to set up.

Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..

Both appear to be a lean mixture problem according to my research. Have you run some injector cleaner through it by any chance? What about coolant level, is it staying up, pressure tested, just in case coolant is mixing with fuel via, head or intake gasket leak, and leaning out the mixture. Low fuel pressure will cause lean mixture in some cases, test it or at least change filter if not done recently, or both. Hope that helps.

2003 Ford Explorer XLT Wants To Stall At Low Idle,, especially when at a stop light


How does it idle in park , does it run ruff or smooth? Are any lights lit on the dash , check engine etc. ? Could have a partially plugged IAC air passage .idle air control (IAC) valve ! The engine computer uses the IAC to control idle , when under a load such as when put into gear the computer raises the idle ! It does this by allowing more air to by pass the closed throttle into the engine raising the idle ! If these air passages clog they restrict the air flow an cause a idle problem ! Now if it runs ruff at idle in park you could have vacuum leak ! Rough Idle How to Fix Ford Taurus Engine Stalls at Stop Signs

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.

Idles rough aand checkengine light on, changed o2 sensor that was throwing the code and didnt fix


Well first, has the vehicle had a tune-up as of late? Second, if it has had a tune-up, then the possible culprit to rough idling is the Idle Air Control valve or IAC for short. Also, if your check engine light is still on, your still getting codes. What are the latest code(s)?

Check Engine light code 1506


Dear Sir,

P1506 error refers to Idle Air Control System Overspeed Detected.
So solution is check your Air control system wires,and check air control speed once again.
If this not solves your problem back with the result,leave a feedback we happy to help you.

2003 sport trac turned over started...died will not restart.


Could be bad altenator, voltage regulator, or battery. If the check engine light is on, it is most likely a bad sensor. The car will have to be put on scanner to find out exact reason light is on.

Starts but won't stay running


Have someone help you do the following. Turn on the vehicle,before it dies,quickly tap the idle air control valve with a wrench or anything you have. If the engine does not die after you tap the IAC,this means that the IAC is faulty. The IAC is under the plastic plate that is behind the throttle body.
