Question about 1995 Geo Prizm
I have a 1995 Geo Prizm 1.6. Yesterday while running some errands the car chugged and acted like it was running out of gas then it died and would not start again. Today I changed the PCV Valve and got it to start. It idles just fine but when I try to give it gas it bogs down and eventually dies. After this happens, when I try to start it, it takes a while but will start and idle just fine. If I feather the gas I can tach it out, but if I try to lets say take off normally, it will bog down and idle rough before shutting down alltogether. I've heard the TPS could be at fault, or the fuel filter, or the fuel pump. I just need some more input, any would be greatly appreciated. Thank you

Try loosing the fuel cap up about 1/2 a turn and then try it out !
if that works replace fuel cap.

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.
