mga sir ask ko lang pag malamig yung engine ok naman sya pero pag long driving and pag mainit ng yung engine lalo na pag naka full stop hindi stable rpm minsan pa nga namamatay...change oil and tune up lang ang ginawa.92 civic lx..tnx...

sir EFI or Carb yung auto niyo?

^ dapat pati yung temperature cooling system ng sasakayan mo (radiator, rad cap, radiator hoses, coolant level and fluid, etc.) ma-chec din IMO.

the idle shoiuld be adjusted at engine operating temp, that is when the engine has warmed up.
What is the initial engine RPM when the engine is cold?

carb engine ph15.when engine is cold 1200k rpm engine warm 900k rpm...add ko po pala after mamatay ng engine hindi naman sya mahirap eh start 1 click lang start agad...ok naman ang cooling system 1/2 sa gauge hindi sya nalampas sa kalahati.pa add din anu magandang pang seal sa thread?may konting leak kasi yung sa thread ng brake line ng master cylinder.tnx...

Pag naka on ba ang aircon nangyayari yan?

Ang seal sa thread gamitin mo teflon.

napalitan na ba sparkplug ng nag-tuneup?
self-adjusting ba ang valve rocker arm o manually adjustable?
yung brake line leak, di ginagamitan ng teflon, malamang may tama na yung flaring o di na-ikabit ng tama yung brake line.

sir sa pag kaka alam ko manually adjustable..napaltan na din ang spark plug ok naman ang idling nya sa first start pero pag long driving na yun d na stable rpm and namamatay minsan..na check na lahat pati carb,fuel filter,pump and cooling system.add ko pa pag mga 2hrs mo ginamit yung car tapos nag park ka ng mga 1hr pag hindi lumamig yung engine as in nasa C yung gauge level hindi satable yung rpm minsan namamatay.hindi naman sa starter or sa ignition coil kasi 1click lng sya.

sir reym try ko po pala lagyan ng teflon.pag naka aircon stable ang rpm 900k rpm hindi ako namamatayan kaya nga sa gabi khit anung lamig naka on pa din yung aircon ko para hindi mamatay pag off ang aircon ayun hindi na stable rpm.

tnx po sa mga input..

Baka po vapor lock? Nangyayari din minsan sa carb engines yan...

wag mo lagyan teflon ang brakes....either cut it then flare (kung may allowance pa) or fabricate another line kung kulang na...steel ang brake lines...don't use copper as replacement....

with regards sa engine mo, since kadalasan nangyayari tuwing mainit baka simpleng vapor lock lang iyan gaya ng sinabi ng isang kasama natin dito....could be the accelerating pump also in the carb. this needs fuel to cool down the accel pump or a sticking fuel float valve assy....check also vacuum lines in the intake manifold as well as gasketed joints...check also the hose connecting the brake booster and intake manifold
