- 08 Explorer xlt 4.0 auto
Now I did it...
My Explorer had been idling pretty rough, put plugs in hoping that would help, but same.
Looking at it today I thought it seemed like idle was just slow.
Saw what looked like a stop screw on the front side of throttle body.
Thought I might be able to adjust and speed up the idle 50-60 rpms and smooth things out.
Well...
I took the screw out and it looked like the thing had been driven way in and there was some of the bottom plastic area that looked like it had came right off.
I checked inside the threaded hole and saw small piece had fallen through.
Took the assembly apart and got the separated piece out of the idle adjusting assembly or whatever I should be calling it.
Took a little to get spring and all of it back but did it.
Replaced the adjustment screw to where I thought it was or close to it.
Went to start the Explorer with hopes of it running smoother but WAY WAY WAY worse.
A couple back fires and REAL rough.
Scanned to see P2104 P2112 and a couple other test not completed codes.
I see all related to idle and throttle.
Tried and tried to clear codes.
Unhooked battery.
Crossed battery cables.
Let sit for a while.
Let idle for a while.
But throttle still non working and little rough running.
I can get one of the check engine lights off but wrench stays lit on dash and no throttle.
Is there any way to fix this?
Almost seems to run good enough, but needs a big major code cleared now....?
Is the screw need to be set with better positioning?
Hoping to figure this out soon.
Can't drive it now.
Freeze frame from scanner below.
Appreciate any and all help.
