Top overhaul daw to clean the carbon buil up!!!

**Ningaskugon** · September 6th, 2005 02:15 PM

Mga sirs tulong naman po.

I have a 1991 corolla GL 16 valve.

My problem is my when my car is parked for 1 to 3 hours it will start on first click but when you turn it off, ayaw na. Puro redondo na lang. (I was about to leave a place kasi and then I forgot something so I turned off the engine, difference of only 3 minutes) When you give it gas it starts but with difficulty then ang idling naglalaro between 500 to 600. When you begin to drive, sinisinok sya.

However after about 15 minutes of driving, nawawala naman yung sinok and idling will return to normal (800) after 30 minutes.

I experimented with the above scenario and consistent yung problema nya. No problem though on cold starts like morning.

Sabi nung mekaniko na nag overhaul ng carb, kailangan daw i-top overhaul dahil marami ng carbon build up. Kailangan daw linisin. Mga 16 valve daw eh ganito sakit.

Less than a month pa lang po ang fuel filter, spark plug, fuel pump and battery.

Tama ba sabi sa akin or nine-negosyo lang ako?

Anybody who can help please?

na pa check mo na ignition coil mo?

Ang suspetsa ko din ay yung ignition coil kaso sabi nya ay hindi coil dahil dapat hard starting na. Pano ba ma-check kung sira na yung ignition coil? Iniisip kong ngang bumili kaya lang kung hindi yun ang problem sayang naman.

yung coil kasi pag malamig ok ang operation nya, problema ang pag umiinit at may problema , nag mimissfire at hard starting kasi maiinit na.

kailangan talaga ma palitan ng working na ignition coil pang samantala para malaman kung yung nga. process of elimination mangyayari yan

bro ..
kung ang hinala mo may damage ang ignition coil mo ...why dont you try to borrow from some of your friends who have the same coil or car ..just to prove na may sira coil mo ..rather bumili ka then hindi naman pala iyon ang sira ..IMO

kung hinala mo talaga eh carbon build-up sa engine internals, i suggest punta ka nlex from balintawak hanggang pampanga. hataw mo lang ng ihataw at 100kph or more. tanggal carbon nya. this is what toyota guys do. (sa casa) to remove build-up ng carbon. this way, mas mura kaysa overhaul at ma-exercise mo yung engine at matakbo ng mabilis-bilis ang makina. after going to and from pampanga, dapat tanggal na ang carbon buildup mo... hth.

i chose carbon clean than top overhaul a year ago sa betan calibration in makati.
pero hindi ganyan ang problem ng car ko noon, dieseling ang problem ng car ko noon kaya pina-carbon clean ko ang engine.

maybe try m muna overhaul ang carb focus on idle jet at ung solenoid valve un kc ngdadala ng idle eh

Get a second opinion... I can't connect well on how carbon build-up affects the starting at different engine temperature conditions?

I'd look more at the carb and ignition system. You may want to change your grounding wires as well...
