Ford F-150 Problem
Engine Affected: 4.9L 6 Cylinder
Average Mileage: 168,416 mi (140,000 mi - 186,250 mi)
Truck starts when cold and runs fine as long as I don't shut it off. When trying to restart the engine while its hot it runs very rough for a minute or two then runs fine again.
When cold, the engine started up and idled OK but after driving it somewhere then shutting it off and trying to restart, it barely started and ran very rough for a while. Pulled the codes out and they were 172 and 211. The 211 is regarding the PIP signal. Replaced the ignition control module ($54.99 from Advance Auto Parts) on the driver's side fender well and now it runs like a champ.
When starting cold,runs great, if I drive downtown and back(30 miles) turn it off and restart, it idles rough for just a few seconds then it's normal
