Hi Have a problem, My 2006 ranger seems to be having a fuel? Problem? It runs fine on initial startup, however after it is warmed up I lose power when I am idling for a long period(>60sec) of time or if I am coasting at highway speeds, The check engine light flashes on and off and I lose power, If I give it gas it kicks back in evetually, Or if I hold the idle up the problem does not occur. Could this be a fuel pump going bad? I went ahead and replaced the plugs, wires, checked the ignition coil and changed the fuel filter to no aviale. Is thier another sensor that could be causing the problem, Thanks Chris

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.

Codes found P0171, P0300, P0303, P0304, PO305, P0316, I also tested fuel pressure seems low 62psi. I appreciate the help I will definitely "donate" as soon as my paypal clears. Chris

So I have two matching things, three if you count the pressure test, Low fuel pressure, I guess either I have garbage in my gas tank or my fuel pump is going bad?
