i have a 2004 f150, 4.6l engine. my truck resently has been dying on me while i was just driving down the road, mostly when i start to slow down. then i start it back up and it might run a little more down the road or just die again. i put my code tester on it and it came up code(P0506) idle control system RPM low. anyone have this problem or know what i can do to fix this or test it.

 

Check the Idle Speed Control motor. If it is stuck, it can cause low idle rpm. Use a screwdriver handle and tap the ISC and see if the idle changes.
