I was getting the engine limp mode problem described in other posts.
I removed the throttle body and cleaned it with carburetor cleaner, and WD-40 for all the moving pieces.
This fix worked great for about 2K miles. Then I got the wrench & limp mode out on the highway.
This time I replaced the throttle body.
While inspecting the old part I noticed a light deposit of oil on the inside bottom half of the flapper valve. Is this normal? (2017 XLT 100k miles)
