Bogging Down 2000 S10 2.2l

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.

It's a faulty sensor could be a map sensor depending on the year of your vehicle or detent cable or throttle body regulator. If I new the year of your car I could help you more.

check the fuel filter and pump flow for starters. Check for cat converter problems. Check coils are ok as they will allow idle but fail at revs.. Check the o2 sensors are clean and check the MAF/MAP sensors are clean also.

Hi looks like mine problem.looking for ideas.Crankshaft sensor or TPS sensor[RPM].I swapped coils and module.No light and what it is?

Check and or change your furl filter

Sounds vacuum related

EGR Valve or vacuum leak

TPS Sensor ?

Have you replaced the fuel filter recently?

I would start there.
It is easy, inexpensive and often gets forgotten about.

If changing the filter doesn't help, you will know fuel flow is not the problem.

Testing your fuel pressure would be your next thing to check. But definately change the filter before that, as it may solve your bogging issue.

I have had your symptoms a few times in the past and cured them this way.

If this helps please let me know!

Good Luck!

disconect egr valve and drive if drove ok replace egr valve

WELL I WOULD CHECK FUEL PSI AND OR FOR CLOGGED CAT. YOU CAN PULL OUT 02 SENSOR AND THEN TRY DRIVING CAR WITH IT OUT TO SEE IF YOU HAVE TO MUCH BACK PSI. IF GETS BETTER REPLACE CAT.

Check your vacuum lines near your intake. Usually with bogging in gears would be a bad front o2 sensor. When was the last time you got a tune up? Spark plugs, wires, fuel filter. Not being up to date on those can cause the car to lose performance.
