    Check Engine Light finally solved

    The check engine light comes on after a few minutes of driving. Turning the key off, then starting turns off the CEL for a few minutes. The engine revs smoothly up to 4100 rpm then stumbles there, then smoothes out above that toward red line. KOEO Codes: 111, 214, 542...

    Camshaft Position Sensor/Electrical Problems

    As stated in a previous post, I have multiple codes on my 2003 Ford Explorer Centennial Edition, 4.6L. After testing my alternator I figured most of them were due to it being weak. After removing countless alternators at the junkyard and testing them outside of the vehicle, I finally found one...

    2000 Limited 5.0 L V8 Throws Code P0118

    So my Black Explorer with the V8 keeps throwing the code P0118. The temperature sensor works as the dash gauge does move with the engine heating up. But the computer keeps saying the temperature is -40 when I plug in my OBD scanner. This issue causes the truck to idle at 2000 RPM randomly, and...

    Check Engine Light with Code 214.

    When I started my Explorer this afternoon(4.0 OHV with 300k) I saw the dreaded Check Engine light. The light came on about a year ago but went off before I could check the engine. I popped the hood and used a paper clip to check the codes, 633(Vehicle must be in 2x4 high or 4x4 high. My gem...

    CEL with code P0102 and already replaced MAF. Please help

    My 99 explorer 5.0 has CEL P0102 low voltage MAF sensor. I have replaced the sensor, the connector, throttle body sensor, IAC valve, gaskets and checked for vacumm leak although there seems to be a leak i can't find after the MAF sensor.

    Possible Electrical or Computer issue?

    All right, so a long while ago my timing chain guides decided it was time to stop existing. My explorer still rattles down the road if I need to go somewhere, and very soon I'll be getting it fixed, so I have a few questions. One, where can I find the reinforced metal timing chain guides? I'd...

    1995 Check Engine Light & intermittent low idle

    My Check Engine Light sometimes comes on, what is the recommended way to figure out what is wrong? Being a 95 it does not have an obd2 port. I sometimes experience a low idle, it may stall if I can't get it moving soon enough after starting. Also, it is worth noting that it has not had its...

    Has anybody else had this problem? I have an 06 V6 Explorer with 135k miles. The check engine light keeps coming on. We have so far replaced the EGR valve, clean out the hose that feeds it, replaced the pigtail wiring that supplies the mass air sensor and the sensor itself. I have been to...

    Check Engine Light/Overdrive Problems

    I have a 2000 Sport, 126,000 miles. The check fuel cap light came on, then the check engine light. The first facility replaced the fuel cap but didn't tell me the code or diagnose it. I don't think they knew what to do other than reset the light. It was fixed on a Friday and both lights were...

    2007 Ford Explorer - never ending Check Engine Light loop...

    Hi all, 2007 Ford Explorer Eddie Bauer - about 116,000 miles on it. Honestly, it has treated me great - and I have also treated it great in return. Always up on the scheduled maintenance, and I've probably done more things to it that are not "needed" (depending on who you talk to) than most -...

    Check Engine Flashing

    All- I recently bought a 2014 certified Explorer XLT with factory tow package at the local dealer. Everytime I tow our boat (the whole reason for buying it), the check engine light blinks when getting onto the expressway, we lose power and the air conditioning stops (only happens when towing)...

    2011 Explorer Crankshaft Position Sensor

    My Check Engine Light came on my 2011 Explorer and after having codes run, it appears it is my crankshaft position sensor. My engine has misfired and pistons 1 & 3 are out. I replaced all 6 spark plugs and that did not do the trick so I picked up a crankshaft position sensor yesterday. MY...

    Check engine light every few seconds, how to check?

    Ok, so I have a problem - there must be a solution, but I cannot see it. The check engine light comes on, then goes off, every three seconds. When it's off, the engine runs fine, when it's on, the RPMs cut in half, it misses, and it has no power / won't go into top gear. It's a 1993 Sport with...

    Check Engine Light

    I have installed an aftermarket Spectre Air Intake on my 07 ST 4.0. I've gotten the check engine light and am wondering what I can do to remove it. Here's what I have. I bought the cone, tube, and everything else separately. The Spectre intake tube wasn't really designed for the ST so I had to...

    1994 70K Miles, but need to fix

    Hi all, Just bought a 1994 Explorer 4x4, with only 70,000 original miles. However, it seems like the stuff that is wrong with it might indicate that the sell shaved off 100,000. I have some problems, such as the CEL come on and stays on, about 5 seconds after is goes out. Second thing is...
