My truck was running fine then lost power started running rough like it was barely getting any gas found that my exhaust pipe was glowing red and catalytic converter too had the checked they were ok changed fuel filter still same problem runs but with no power and runs rough
When starting on cold days starts great. On hot days hard to start. It finally starts but you think this is the time it won't start. The engine sounds like someone is blocking the tailpipe--like its choking and coughing. The engine light comes on.No one has been able to fix it. By the way, it has 2 fuel tanks and is 4x4. I have been told to open both fuel caps to help start it. I have also been told to turn the key to the right 3 times before trying to start it. Someone else told me its probably vapor lock. Again, on cold days and during the winter it seems to start better. This started around 50,000 miles. It now has around 89,000.
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.
