Bought a 93 Ford Explorer replace fuel filter car

Please see my tips at link below.
Do It Yourself Diagnosis and Repair

new spark plugs this decade. (a tune up?0
the filter is part of all 60k tuneups. letting it clog wrecks good pumps.
my wild guess, its lack of fuel flow, do to old filter.
or low fuel pressure.
car is identical to a Corolla. so is not unique or rare as some Geo cars are.
the cam belt not changes, invites valve kissing piston tops. BOOM
end of engine. (costs more to fix then worth of car)
the word is bogging, my engine bogs
if if bogs WOT (wide open throttle) and dont catch up < ITS NOT THE TPS. ever.
tps bad causes short bogs, called hesitations.
The map sensor , is what measure air flow and the ECU matches fuel to this air flow.
my guess, is it does that, but fuel pressure is like 15PSI, bad.

Check and or replace fuel filter and or fuel pump. Use fresh fuel if it has been sitting a long time.

Check the fuel filter is not on backwad if this was helpful please leave good feedback

Check your air filter, Clean it out or replace with new one.
Check your fuel filter, replace with new one if needed.
Check your carburetor for anything obviously loose or vent/ vacuum hoses displaced.

sounds like catalytic converter is going bad? put your hand by exhaust pipe and have someone rev engine. if not much exhaust coming out then converter is about to get clogged up. had the same prob 5 years ago. another question......when you are driving and give it gas does it take a while to gain speed? if so it's definitely the cat converter.

You may have a fuel issue the cheapest thing to do is a simple fuel filter replacement an old filter can cause backups in the gas line. Also check to make sure your air cleaner assembly is fully hooked up and no hoses or clamps are loose. less air cause these same symptoms.

mass air flow censor

I didn't see where you mentioned the MAF, or mass airflow sensor, my Volkswagon had the same problem. If I drove for more than 30min, the engine would basically bog, and sputter until basically you couldn't go but a few mph. Then you sit and wait maybe 20 min, and it ran fine for another 30min. Almost posotive!!!

You probably have a clogged fuel filter. There should be an inline fuel filter between the gas tank and motor, replace that and your good to go. I have the same problem with my c10 pick up.
