What is it with these Explorers ?
I used Premium gas and Seafoam and seemed to help a little.
The vehicle was totaled before the problem was solved.
About 2 years ago she bought a 1997 Explorer sport 4X4 that did the same thing only worse it would start cutting out at lower RPMS also.
Once it was so bad I could barely get it to move, so I turned it off about 5 minutes,started it back up and it ran fine. (problem never resolved and vehicle is gone) I always ran 100% gas and put in Seafoam every time I filled it up !
She just bought a 1992 XPL Sport 4X4 and it seems to be doing the same thing the Bronco II was doing only not quite as noticeable.
I want to resolve this issue before it gets really bad !
Anybody have any answers, cause this has to be a problem in a lot of the Explorers!
1) pull codes from the computer in case the computer sees the problem (this can be done with nothing more than a paper clip: put "ford eec-iv self test" into your favorite search engine).
2) Put a fuel pressure gauge on it and see what the fuel pressure is doing when it hesitates. If the pressure is dropping off, that suggests a problem with fuel delivery.
3) Check for vacuum leaks.
4) See about any tune-up items that might be due for replacement.
I will have mechanic friend pull the codes Saturday and see what happens.
pbjohns, I have lived in the same house here for 20 years and have gotten my gasoline at a local Quiktrip which has good quality gasoline although it is 10% ethanol.
I have had many vehicles over those 20 years and the 3 Bronco/XPL are the only ones I have had problems with.
The 97 XPL was always filled with 100% gasoline at a local Sinclair and always kept a can of Seafoam in the tank.
The 92 also has no Cats at this time !
FYI my 1988 F-250 has similar problems!
Seems like all the fuel injected Fords are giving me fits.
