I have a 99 ford f150 i replaced the fuel pump sensor filter fuel and air and my truck still stutters and stalls? I'm teaching myself to work on this truck so its not easy just kinda at a loss with this any help would be appreciated
-
What is the engine size of your F150? check and clean the Mass Air Flow (MAF) sensor, sometimes debris block the air flow and cause the symptoms and code you describe.
-
Ok im gonna try that tonight i have a 4.2 i was reading a few things about the egr and trans speed sensors causing the same symptoms is there any truth in that?
-
Yes, both things can also trigger the same symptoms. According to a national database of repairs for your model year, one of the most common causes that could trigger the P0176 code after the MAF is the Fuel Filter.
