Go to the auto parts and get a throttle body cleaner and clean your air flow sensor the air flow sensor measure the amount of air coming in and this tells the computer to send more fuel so if this is dirty it will not measure the right amount of fuel and it will shut off the engine

Car idles fine, but sputters, bogs and dies if gas pedal is pressed.


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.

3.1 Motor bogging out.


Hello
The engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Starts fine, but then bogs out when accelerating, practicaly have to give it no gas and creep up to speed.Doesn't want to go up hills. Just replaced the cpi, fuel filter and fuel pump 3 months ago. Also...


Check the fuel pressure regulator and the EGR valve, I would check the fuel pressure regulator first and go from there. Good luck and keep me posted. Not sure what the pressure should be but thinking it's 62 to 65 PSI upon start up and should drop 5 PSI when engine running, check the vacuum line to the regulator.
