2013 F150 4x4 5.0 I was off work, it was warm enough and not raining (yet), and I had all the supplies this morning. Gave the truck a much needed oil change and new oil filter (both Mobil 1) And finally gave the Mass Air Flow sensor a cleaning. Used CRC MAF cleaner. 49K miles Also changed out the air filter. Cause I was in there for the MAF sensor. Seems to be running much better. Had an Idle stumble that seems to be gone. Used Forscan (got adapter for Christmas) to look at the MAF readings before and after. Don't remember the #s but it cut the Grams per second in 1/2 (better). Only bad thing was I had to lay in wet melting snow to get under the truck. Got done and cleaned up and the rain started, Good Timing. ---Nailer---
Keep an eye on the upper raidator hose and thermostat connector they like to leak. It is a quick connect type connection if you grab the upper hose and give it a good squeeze and wiggle you may see some coolant leak out.
Good work. Better to get it done now than getting stuck on the road! I just joined AAA plus with the free 100 mile tow - their road side service is good,
