Vespa S125 | Check Engine Light

Starting to experience some problems with my Vespa scooter. Stalling at low RPM and idling, and the check engine light is always on. Did an ECU scan at Stella Moto Lifestyle which showed that I needed to have Throttle body cleaning and Fuel injector cleaning, did both and problems still persisted.

Check mo spark plug/ignition coil sir pati yung MAF sensor (di ko sure kung meron ganito sa scooter). Kasi ganyan ung naging problema ng sasakyan ko same na same ng scenario gaya ng sayo.

turns out this was the answer all along, the scooter works fine now. hindi yung airflow sensor yung problem but the hose that goes to the sensor and the breather tube, sila yung madumi. after cleaning them, back to regular running condition na yung s125. (pero check engine light on parin, oh well)

waiting for update same tyo ng bunso anak na ginagamit sir, kuya version nga lang yung sa akin 2018 model non usb,. ayon kay chat gtpi sabi eh Fuel System Problems, Ignition Timing Issues, Spark Plug Issues, yan possible issue, mahal pa naman mag palinis ng body throttle ng vespa at ang tagal, buti nag lilinis sila ng fi. advice ng mechanic ko eh no need na linisin ang fi wait na lang mag sira.... kung sa akin mangyari yan d ako masyado mapakali at makakatulog

2018 din sakin sir non-usb. Spent 1500 for the ECU scanning and 800 for the labor, nasama na yung throttle body cleaning dun sir. yung sa FI, hindi talaga yung full cleaning na may machine, more of binugahan lang. had everything done in one afternoon, di naman siya super tagal.

@@kwentongkalsada sana maayos na, waiting for the update. kahit ako na papaisip na pwede pala mangyari yan kahit nag throttle body cleaning na at fi

May one last adjustment yan sir. yung sa throttle cable ko, need nalang taasan. pag naka idle ako, nilalagyan ko ng onting onting gas para tumaas yung menor niya and di siya magstall. If, maadjust na yung throttle cable, then most likely aayos na yung timing niya para sa menor and maiibsan na yung pag-stall niya sa idle. Salamat sa laging pagsubaybay sir!
