Hopefully you are not the original owner of the vehicle, because otherwise
it sounds like your air filter has not been replaced in 15 years....
Look for a black box, connected with a large diameter (3" or so) hose to the
top of your engine. Not sure about the 1990 model, and not sure if it's the
same for all engines (you didn't provide that info), but it's probably in
the front passenger corner of your engine compartment.
And you know what? Your user's manual will have the exact information,
including how often to replace it -- with a picture to boot!
Didn't they start building explorers in 1992 ???????
Anyways, just in case it is a typo , its that round plastic thing behind
your r.h. head light
There is a clamp around it that you open, pull it up and pull out a paper
If car is a lot newer it might be a flat square paper thing
You're probably way overdue on the filter change but what "they say" is a
lie. It DID make a big difference in carbureted cars
The average driver ( who rarely puts the pedal to the floor) wont notice
a dam bit of difference... BUT dirty air filters lead to dirty MAF
sensors and THEY will cause performance problems.
And gonzo plugs wont give you 10% better mileage, either. If they did,
wouldnt the Mfrs use them in the first place?
Neither will the "Air Spinners" you see on late night commercials..If
they did, wouldnt the Mfrs use them in the first place?
And when they talk about tire inflation and mileage, they're talking
about BIAS ply tires which no one in their right mind buys anyway... even
if they can find them. Of course with an explorer, you keep s your
inflted properly anyway, unless you have a death wish.
Sidenote: Once saw a "professional" demonstrate how driving 55 saved 15%
on gas compared to driving 65.
He did it on a small road course track with a corner coming up every few
hundred feet. IOW, he was a liar.
If it's "Conventional Wisdom" and you hear it on the news or a
commercial, it's probably an exaggeration at the least.
But the topper was a cop on local news discussing a congested area of
freeway who advised everyone using that stretch to slow down and leave
more distance between cars... what a freakin' idiot!
I decided to visit a "Break Specialist" where I normally frequent and have a
friend working at, and found out why I didn't see the air breather I thought
I should have been looking for, the vehicle is a fuel injected engine and it
doesn't have a normal breather like a car with a carburetor. The mechanic
pulled the filter out and showed me it was pretty much clean (simply needed
to the small dust blown out).
Thanks for your information.
