salam,
so after painful 2 weeks, i have managed to figure out whats causing surging/fluctuating idle of my car.
today when i got back home from office, took out my rachet kit and took out the airfilter box of the car.
what i see will blow your mind, the sensor behind the throttle body which is screwed to throttle body was moving freely and no nut/bolt was holding it with the throttle body ( i have been told its a choke sensor which adjust the timing of the car as per the load on the car)
3 weeks ago this car was fully tuned by HONDA 3S Peshawar road Rawalpindi, i spent 12000 rupees at HONDA. Honda guys did tappet adjustment, throttle body cleaning etc.
they guy who did my car forgot to put in these 2 (both) ALLEN key bolts back. the sensor was roaming around free.
Attaching the below TWO videos, i was sharing these videos with a friend who was guiding me what to open and what to check because of bad idle.
what you are about to see will blow your mind.
below video will show you in which state if found this sensor.
and then below video after starting the car and checking idle stability after holding sensor by my hand.
going to see HONDA tomorrow.
