Ford F-150 Problems

Rough Idle Caused By EGR Sensor Sticking on Ford F-150

Problem Description and Possible Solution

The Ford F-150 is known for intermittent rough idling, which may be accompanied by illumination of the check engine light, and poor fuel mileage.

This may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open, and diagnostic testing must be conducted.

The EGR valve and sensor must be replaced together to correct this concern.

rough running n park run good going down the road coming to a stop start running rough again
missing went warming up to
After I have driven a while and stop at a stop light the truck would idle rough. We could put it in neutral and it would subside. I have had the egr tube replaced and will see if that takes care of it.
It runs fine at highway speed but it doesn't idle properly also has check engine light on
im not sure if my problem is this or not but lately my truck will stall if it is ideling or i am slowing down. It usually only happens also if i have the air conditioning on.
Runs rough after 30 minutes of driving our gets warm go to idle it sounds like a diesel truck running shut off and restart it does find for a little bit
Stutter or rumbling from low speed acceleration. Highway speed seems to run better. Cleaned MAF + Air Filter, checked TPS, no obvious vacuum leaks. Need to run a code reader still, may be a coilpack/spark issue, or possibly emissions? Still have not fixed.
Motor starts good but idles rough and has no power until warm but still missing. Codes say plugs#2,4,6,8, too lean and 02bank1 bad. I changed plugs and sensor. Last week I changed EGR valve too but not EGR sensor, where is it?
