    Hello mga sir! I would like to seek for your expert advise regarding on my problem I've experience on my Nissan GSX and I'm just in car. As I start the engine, the idle rpm abnormally drops down near zero then after approximately 3 secs it goes up to its normal idle rpm of 650 and I already encountered this twice. Ano kaya problema nito? Actually, I'm planning to bring it to the CASA since under warranty pa naman ito. Gusto ko lang po sana pagpunta ko doon alam ko na po ang sasabihin ko. TIA!

    If still in warranty it is your best interest to bring the car to dealer to fix that problem.

    could be the servo or a dirty throttle. shouldn't be that hard to fix on a relatively new car.

    Is the engine cold or warm?

    it has to be checked by the tech , pero you can ask the dealership to get it scanned for any codes or to perform some basic tests.

    i.e.smoke test for any vacuum leaks or a throttle body cleaning maybe.

    hi Yen,

    just saw this thread. i had the same problem with my Sentra as yours after i had my headlights changed to XP sa Petron. I don't know if meron sila nagalaw or something, but the idle RPM dropped from 850 to 400 with A/C, 300 if walang load.

    brought it to NGO- Libis, kinabitan lang ng Consult II, then dun in-adjust yung idle RPM back to 850. ayos na ulet.. la pang 10mins.

    SA Remo ang nag-assist sa ken. Hope yours get fixed as well.

    Cheers!
