Need help!

Hi guys i have a nissan cefiro 99 model. Ang problem is ok naman sya pag start tapos habang umaandar bigla nalang namamatay kahit nakaapak ka sa gas as in sunod sunod namamatay pero pag iniistart naman ok sya. na try ko na palitan yung fuel pump, and fuel filter and ang dami na din tumingin na mekaniko pero hindi nila makita yung problem. pa help naman po kung alam nyo yung solution thanks.

try to clean up the throttle body first.
change plugs
check the distributor
check hi tension wires.

Hi sir na check ko na din pero it seems wala naman dun ang problem. may times na parang ayaw din humila sasakyan while stepping on the gas and mamatay sya pag inaapakan yung gas. pero pag naka idle naman ok lang naman.

Fuel pump malamang faulty na. Hanap ka ng reputable mechanic sir. Check with nissan forumers.

Peace out!

Mahirap humila? Does the RPM rev freely at neutral? When you're running at gear, nahihirapan to go over a certain RPM? If so, try to check and clean the MAF sensor.

Try checking baka ikaw yung kapit-bahay nung sa kabilang thread tapos nilagyan ng patatas or kamote tambutso mo.

sir as in di humihili at times tapos yung tunog ng engine is parang nabubulunan pag inaapakan mo yung gas pero pag binitawan mo yung gas ok yung tunog ng engine. though at time kusa nalang mamatay.

kapag tinatapakan mo yung gas, nagrerev ba yung engine?
had an issue with my sentra, hindi nagrerev kahit tapakan yung gas pedal while driving especially sa inclined road. found out, it was the fuel system wiring ang faulty. maluwag yung harness sa may distributor kaya hindi nagrereact ang fuel pump

i spoke too soon. had the problem again. engine won't rev past 1700 RPM when running. kapag idle no problem sa pag rev.
still observing pa.
