2006 Explorer EB 4.0L was created by Msober1
Have 4.0L Explorer with no DTC no driveabilty problems. No vac leak, clean TB good Temp sensor. When cold start engine rpm goes as high as 2600rpm. Scan reads desired cold RPM 1385 but actual will go 2100 to 2600. Warm engine start normal. Does anyone have any good cold start data from a good running Explorer 4.0 ETB or any help. I’m not sure if anyone before me has done anything to the TB like tried to adjust the stop screw. I contacted Standard Motor Products tech’s at their TB rebuild shop and asked if they had any settings for that idle or minimal blade opening set point and guess what they don’t touch it because it’s set by OEM. I said what if someone screwed with it he said they can’t. Ha ha ha in my 45 years of mechanical work if it has a adjustment screw someone will fu$k with it.
Any help before I go to get Ford dealer and order one. Ty also wanted to add I’ve done the Ford throttle relearn.

Almost sounds like a intake gasket leak when cold then seals up when warm. Any chance you can smoke it cold??

Sorry I didn’t list that. I did that all ready. I don’t understand why the in less than 1min it comes down to close to desired like 1400 to 1500. More like 20 or 40 seconds.
