Mga paps pa-help sa mga naka-experience na, share your ideas naman.

Yung car ni esmi nissan sentra B14 EFI, pag start then pag bitiw ng gas pedal deretso sya namamatay.
Already changed 4 spark plug, clean the injectors malakas naman ang flow ng gas sabi ng mekaniko. Sabi ko try linisin ang servo, kaso ginabi na balikan na lang daw bukas.

Baka puede nyung i-share ang mga naging solution nyu sa mga naka-experience na. TY

P.S.

I tried to back read na pero wala akong makitang nag post ng direct solution that they did, kung meron man paki-share na lang ang link.

idling rpm too low?
increase it?
too little air bleed?
if yours is like my ECCS, look for a large recessed screw on the right side, under the air cleaner housing... baka purple yata..
using appropriate screw driver, make a 1/2 to 3/4 turn, counterclockwise.

remember exactly what you did, because if it gets worse, you must return the settings to what they were before.
then look for professional help. there are some nissan shops somewhere.. banawe..?

good luck.

Might be a servo failure. I suggest clean your throttle body and servo and maf sensor first and tune it. If the problem persist check your other sensors like temp.exhaust etc. clean them also. If still the problem persist try to borrow a servo and test it before buying one just to make sure if that's the culprit. The servo is the one which maintains your idling so i suspect this might be failing as it controls air in idling mode.

yes, same here. have the throttle body and all related sensors cleaned up first.
actually, naging problema ko din yan before, but after cleaning, everything was ok na.

Pinalinis ko sa mekaniko ang servo, and mukhang sa harness plug meron problema, kapag naka diskonek ay hindi namamatay ang engine pero kapag ibinalik ang plug doon sya nagshu-shutdown.
As of now, nagpapahanap ako sa mekaniko ng replacement either bnew or surplus pinadala ko na lang ang mismong sample, and hopefully everything will be normal afterwards. Update ko kayo later-on mga paps.
