If you haven't replaced the spark plugs or coil on plug units, that could also cause misfires, but they would also cause a code which you have not mentioned.BernardLhttps://www.blogger.com/profile/09722619048888613647noreply@blogger.comtag:blogger.com,1999:blog-1405576651020920367.post-82391969170854432772019-11-04T11:20:04.967-08:002019-11-04T11:20:04.967-08:00First, Autozone and Napa do not sell OEM Ford part...First, Autozone and Napa do not sell OEM Ford parts. Anything, such as a sensor or catalytic converter should be OEM from the dealer. Here are some things to try you may have missed in the post.<br /><br />1. If you have multiple throttle codes, it will almost always mean an electronic throttle body replacement along with the throttle position sensor.<br />2. The wiring harness running behind the Exhaust Gas Recirculation tube chaffs through the harness wiring and causes a multitude of goofy sensor and code problems.<br />3. They have updated spark plugs for these. In a related note, misfiring coils and spark plugs also cause an array of unrelated codes. My advice is change both the spark plugs and individual coil on plug assemblies every 60,000 miles.<br />4. The alternator going out on the Expeditions can and does cause electronic interference, disrupting engine and transmission operation.<br />5. A link to the Technical Service Bulletin for Transmission and Drivability problems related to a check ball breaking inside the transmission valve body.<br />6. I came across myriad problems in the East and Midwest after much research where a leaking windshield leaks water into the fuse box. The fuel pump relay is built into it so the fuse box has to be replaced when leakage is found. If the C270 dark green wire at the fuse box has no power it would point to corrosion in the fuse box. That could also cause myriad weird other electrical problems.BernardLhttps://www.blogger.com/profile/09722619048888613647noreply@blogger.comtag:blogger.com,1999:blog-1405576651020920367.post-60209398874167195182019-11-02T08:56:08.108-07:002019-11-02T08:56:08.108-07:00Hey, I have a 2006 expedition with 120k miles on i...Hey, I have a 2006 expedition with 120k miles on it, I having a problem when I get on the highway I can't go over 70 and if I hit the gas hard I feels like it misfiring and will not go.

I did find this mention of a problem like yours, requiring a heated PCV valve kit from Ford. The TSB in the article isn't for a 2000 Expedition, but you may want to see if there is such a thing for yours at the dealer. Sorry, but that's all I can tell you.<br /><br />My throttle sticks in very cold weather (I'm in Yellowknife, so it's very common to have steady -30s for several weeks). Not only is this not too good for the engine in general, but it is also very dangerous. In fact I almost crashed into the Ford dealer's garage yesterday trying to stop the vehicle with the engine revving at 4,000 rpm! Luckily, nobody was in my way, but it was a scary experience with a vehicle of this size. There is a Ford TSB (#012112) confirming that this condition exists on few vehicle, and the fix is to install a heated PVC kit to replace the original. If the vehicle is still under basic warranty, no problem. If it isn't, like mine at 66,000 km, then you're out for about a $1,000 repair bill. So far the dealer has refused to cover the repair for me, even if I bought the vehicle less than a month ago, with Extracare ESP. Any advice or suggestion would be appreciated. If anyone has the TSB, I would appreciate a copy via email if possible.BernardLhttps://www.blogger.com/profile/09722619048888613647noreply@blogger.comtag:blogger.com,1999:blog-1405576651020920367.post-16419617302878383342018-01-12T07:51:36.103-08:002018-01-12T07:51:36.103-08:00Lol that makes complete sense.

In the case of the 2000 expedition throttle sticking wide open only when it's crazy cold and driving about 10 miles on highway or interstate, where is the next place you would look after making sure the throttle body cable isn't jammed or kinked and the external parts are moving and returning to the right positions?

Only way to come to a stop is to turn the key off. I got under the hood and flicked the throttle body open and closed quickly to maybe loosen anything stuck but that did no good. The return spring is good and tight.

While going down the highway, keeping up with traffic, my rpm hit 4000-6000 before my transmission will shift in or out of overdrive. And when it does shift it's stuttering/bcking/acting up. When I do get an engine light the only codes that I get are coils. All have been replaced along with the intake has been replaced. I can't for the life of me figure it out.

From the day I inherited it it has been one problem after another. My current situation is: while driving down the street at about 29mph the gas pedal would rev but quit delivering power to the drivetrain. Their were no prior indicators of anything wrong with transmission. shifted fine right from start up. It has now sat for several months. I put some seafoam and 5 gals of fresh gas and it starts and runs fine. I've only ran it for about 5 minutes. put a code reader on it and codes p1537 & 1538 come up, intake manifold runner control banks 1&2 stuck open. Called around and noone has heard of such a thing.
