Asked by Jndgh67 Sep 19, 2017 at 05:01 PM about the 1998 Ford Explorer 2 Dr Sport 4WD SUV

Question type: Maintenance & Repair

Hello,my 98 explorer 6 cyl /4 whl,started missing
and stalling like it was running out of gas,after I'd
sit for 15 -30 minutes,it usually starts right up runs
strong and smooth,and might for a couple day's,
then acts up again.So far I've replaced the fuel
filter ,the mass air flow sensor,cleaned what I could
reach of the intake,and sometimes this helps ,and
today it started fine ,run like new til I got ready to
leave work and now here I sit like it's out of
gas.One time it smells gassy,and won't start,the
next like it has no fuel.Any suggestions what to
change next ? From what I've read here ill do intake
gaskets,but im not sure about coil packs?Thanks

OK i'm stumped. I have a 2001 ford explorer(please keep comments about fords to yourself ). I've had 4 episodes where i was driving along with no issues and the even though i am excellerating the car stops running and the stalls out. Once i pull it to the side of the road and try to start it it back fires and qcts like it it out of gas but if you wait 30 plus minutes it will start and run for a bit longer then repeats itself a couple more times but then it will runs for days until it does it again. The check engine light is not on but the check gas cap is on. we replaced the gas cap and it is still on. The first time this happened I had it towed and the mechanic tightened the serpentine belt and fixed the manifold gasket. Does anyone have any ideas???? 14 Answers
