Bogs when acelerate idles fine

I had a case tractor with a 4 cylinder diesel, dual heads, in-line cylinders. It had a similar symptom. Turned out to be a cracked head. Only one of the two. Water pump had previously failed, this led to overheating and cracking of the head.

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 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.

Check or replace the fuel pump control unit, common problem on the 720 models. It is in the right kick panel near the glove box. The part costs about $60 from Nissan.
There was also a recall on the ECM relay-causing surging, bucking, stalling, instruments go crazy. Relay is in the box at right rear of engine compartment.
Have you replaced the fuel filter and checked the air filter?

Try checking the fuel filter or the fuel pump.

check your fuel pressure, it is either fuel pump, filter or regulator issue.

You could possibly turn up the idle if it bogs down when idling. If it only bogs down when you press the gas it may be a clogged fuel filter or fuel line. Could also be your fuel pump starting to go if you ride with less than a quarter of a tank of gas most of the time.

i had a van do this same thing to a tee turned out to be a broken key pin in the harmonic balencer causing the timing to ****** replaced balencer and ran like a dream there is a crank sensor grid on the balencer when the key pin broke it trew the timing off

check for a dirty fuel filter

It could be a lot of things, if you can run some component testing. You should be able to narrow it down. Test the TP, EGR, IAC sensor, Look, does the car act up at high throttle while in neutral or just when its in gear? You may want to check the timing and look inside the distributor for any signs of water, rust, or carbon build-up.
