Naghehesitate pag unang andar

[scanner]

Mga sir : Lagi pong naghehesitate sa initial andar yun 96 Mit Lancer EX ko (especially pag umaga) pero pag uminit na makina ko nawawala naman . Bagong tune-up po, ok naman timing, at naka synthetic oil. Problem is hindi madiagnose properly kasi by the time I reach the shop ay hindi na po mareproduce yun symptoms nya. Babalik na lang po the ff morning uli. Carb problem po kaya? Tnx for your help. :confused: :confused: :confused:

yup, baka stuck ang choke.

Dirty fuel filter.

We had the same problem with our Tamaraw FX 1.5 liter gas na de karburador. If de karburador pa po ang car ninyo then baka madumi na ang karburador. Malaki magagawa ng mga karburador experts sa Kamuning kung ganoon ang problem. Pina-clean namin karburador for 350 pesos at solve na ang problem.

Bukod po sa maduming/baradong karburador, check nyo rin po yung spark plugs, contact point, fuel line/filter........

naging problem ko din yan dati eh......


i hope this can help, goodluck!

scanner,
nagkakaproblema ka rin ba minsan at "ordinary" speeds. tipong kahit anong apak mo sa accelerator, hesitant at minsan nag-bo-bog yung kotse?

could be carb, like what the others said.....or a "fuel pickup problem"..... medyo ganyan din kse yung kotse namin e

Thank for all the advice. Had my carbs cleaned at Kamuning (mahusay nga po dun!), complete tune up (again..hu hu hu) with new orig Mits spark plugs. Bago na din po yun fuel filter. Then tinest ko the ff morning. Medyo andun pa din po yun problem pero mas mabilis na ngayon mawala at pagnormal operating temp na po engine eh swabe naman. Do you know any other possible causes which I might have overlooked? Di kaya mabagal pa umikot yun Fully Synthetic oil 10W-40 ng Petron? Maraming salamat po uli.

Try another set of ignition cables, the old set may be low on voltage.

dati b hindi naghehesitate lancer mo pagka-start a umaga??
check also the hi-tension wires. in the case of the synthetic oil, dapat nga mas mabilis umikot sa makina mo yan kasi mas mapinis ang synthetic oils.

di ba talagang medyo hesitant naman lahat ng makina pagkastart, (lalo na pag malamig) kasi below normal p ang engine temp tsaka hindi pa nakakaikot masyado ang motor oil? thats why its not advisable to rev & rev the engine after u start it in the morning. its best to just let it warm up on normal idling.

benchph1 : actually kahit after 3-5 minutes ng warm-up idling without revving andun pa din po yun hesitation. I think its enuff time for the oil to circulate.Yun initial 10 meters talaga ng andar ko nararamdaman yun problem .papacheck ko din yun cables. Autoelectrical na po basta cable or tension wires , di ba?

Had the car checked. Ok pa naman daw yun tension wires and distributor cap. hoses are intact. Explanation : Piston rings are not yet warm and expanded. After warm-up, they naturally expand therefore creating a tighter seal hence better compression. Natural na daw ito pag nagkakaedad na ang engine. Does this mean hopeless na itong problem unless ma-overhaul? Appreciate all responses.
