    mga pre,

    advice naman dyan, sometime this month magpapa-service na ako ulit (honda shaw)... kaso, may idling prob na kotse ko (civic sir) for about a year na... yung problema ay bumababa ang idle from 800-1000 to mga below 500 rpm, pero hindi namamatay yung makina... ang ginagawa ng casa, isa-isa nilang chini-check yung mga possible culprits...ang nagawa palang nila ay overhaul ng throttle at may kinalikut sila para umangat yung idle ko, kaso ganun pa rin...sa kotse.com, may nakolekta akong mga parts na possible daw na culprit: fuel pressure regulator, electronic sensors, pcv/pvc?, TPS (throttle position sensor), idle compensator/up, idler bearing, auxillary fan for aircon, condenser...

    may mga naka-experience na rin ba nito?! tama ba yung mga culprits na na-mention ko? para pag-punta ko sa honda, isang gawaan nalang!!!

    sana matulungan niyo ako!!! maraming salamat!!!

    Is your civic sir modified and what have you changed? How many kms have you run? Do you bring the car on out of town trips? Is the idling low with or without aircon?

    Had idling problems on the Crv last year, all i did was to spray carb cleaner into the throttle body which removed the gunk blocking the vacuum lines. If the casa cleaned this, then check all the vacuum lines for leaks.
    The TPS should not be adjusted since this can really mess up idling if you don't have the factory specs for its exact setting.

    Possible Vacuum hose leaks... check all the little hoses for leaks or cracks.

    this is a very similar problem in my civic 2005 manual. based on my observation, naging obvious lang tong idle dropping yo about 500rpm pero ndi naman namamatay yung engine pero naagapan ko by revving up a bit. typical to kapag mainit talaga panahon at stop and go ang traffic. mas madalas mangyari to kung stop and go pero during long drive ndi naman. pero kung nakatigil ang sasakyan meaning full stop or just in parking when i jerk the gas up and release suddenly ndi naman bumabagsak ang idle. naka ilang pasok na to sa honda magallanes pero ndi nila naresolve instead tinaas lang yung threshold ng idle up during aircon on and rev down para ndi totally bumagsak ang idle. i believe nararanasan ko na to as early as 2010 pero ndi ko napapansin kasi ndi pa ganun ka obvious ang prublema. naging obvious lang ang prublema netong 2016. i wonder kung naresolve na tong prublema sa thread na to para me guidleline naman ko how to proceed. i am suspecting an O2 sensor issue or electrical problem in my case.

    For 90’s Hondas, 99% of idling problems can be resolved by cleaning the throttle body & IACV

    What could be the other culprits if MAF, TB are already cleaned and hoses does not have leak,new plugs and coils. Minsan may hesitation din
    pag uma andar na.
