My 2006 Ford F-150 I recently purchased after getting warmed up to operating temp the motor wants to start running bad and die at stop signs or low rpms. It is driving me crazy!! I changed camshaft sensors and Vct solenoid also gave it an oil change but to no avail. Someone please help!!! Thanks. Tyler

 

Before we do anything , was the battery recently disconnected and reconnected?
Also remove the intake hose from the throttle body at the mass air flow sensor and check if there is any accumulation of crud/ carbon on the throttle plate and mass air flow sensor that extends into the air intake. If so there is a special cleaner used to clean the sensor and throttle body butterfly. Once that is done the throttle body recalibration should be done so The computer knows the unit has been cleaned and adjusts accordingly. Let us know what you found because it is a little lengthy to explain if not necessary.

 

Ok so I took some throttle body cleaner to the throttle body and it seemed to help the truck a little bit bit the problem is still occurring. The code that comes up now says intake manifold runner control stuck open bank 1. Asked a mechanic buddy of mine and he told me he didn’t think 2006 5.4 had a Imrc?? If it does where would it be located? Thanks.
