A couple of weeks ago my 1998 F150 w/5.4L started running and idling rough and has stalled a couple of times. No "check engine" light. I changed the fuel filter and cleaned the throttle body and mass air flow sensor. Though it ran better for a couple of days, the problems have returned but not as severe. In addition, I now have occasional problems starting the engine. It cranks fine and finally starts after 3 or 4 tries like it is starved for fuel.
Also, during this time my fuel gauge stopped working. At first it would drop to empty but in the morning it would be functioning again. It would work for a couple of days but then malfunction. The last 2 days the gauge shows empty when I have at least half a tank.
I'm not sure the two are related.
Thanks in advance.
have the same problem?
