So,do i still need to make the engine a liltle hot before driving it if im using the cold spark plugs? o sa hot plug ko gagawin yun? Sorry,im confused...
Oo nga pala,today ok yung andar nya. Walang nginig sa 1st gear. Im still using the same spark plugs(bosch platinum).

Do you guys observe kung ilan ang rpm nyo sa 100kmh? Mine is at 2,500...

What is the number that indicates your sparkplug number is hot or cold plugs. if your plug is a cold plug and your engine doesnt run for long period of time it will not get the right operating temperature immediately. hot plugs easily gets its operating temperature even with a short period of time.

eto solusyon if i were in your position...

check if may hangin sa clutch and brake lines, if meron, bleed lang yan then refill. di pa ba sliding ang clutch mu?

change your platinum SP to stock, if andun pa din problem mo, check mu yung engine idling, kung mababa agad kahit kakastart mu pa lang ng makina(morning cold start), pacheck mo na sa mekaniko. i recommend NGK sparkplugs, it is the alternative SP for denso , and also used by toyota itself.imho bosch sucks! busina lang ok sa kanila

when ka huling nag change ng transimission oil? i assume na manual ka, so baka due na for pms ang gear oil mo.

and lastly, anung viscosity nilagay mu nung nagpachange oil ka? baka its too heavy kaya medyo hirap makina mo.

try to reset your ecu also, tanggal ka lang battery for `10mins. then start without revving it.

kung lumitaw ang problem mo after installing the platinum plugs then just get the oem plugs then see if it will solve your problem. oem plugs are cheep naman

Ok naman idling ko,pag sa morning above 1k,then after a few mins bababana sya. ito mga previous upgrades ko sa auto,Palit mags(16s-19s, Palit air filter KNN, Palit na din fuel filter, Spark plugs. Its been 3 days since nag post ako dito,as of today ok na yung andar nya,wala nang nginig. Take note,yung bosch padin na SP ang gamit ko ha... So ano kaya nangyari nung mga araw na may nginig kada malamig yung engine???

Nag iba din FC ko,from10km/lit city naging 8.3-8.8 km/lit nalang... Malaki kaya naging part nung mags ko sa naging difference ng FC ko? May nakita akong thread dito talking about KNN. May mga nag comment na nung nag palit sila ng KNN filter nag bago FC nila... Akala ko ba more HP plus better FC yung ibibigay ng KNN???

its a good thing your engine idle is ok now without doing any replacing again.probobly the fuel filter also contributes to your engine rough idle, it might cause some restriction so the engine hesistates. well regarding the fuel consumption, the big wheels has a big effect even though you have upgraded your air filter to a high flow KNN. more power means more fuel to burn to equal to the power. at the same time big wheels are hard to rotate than smaller one. big wheels will only benifit you on long travels because you will only need fewer rpms to reach your desire speed compare to smaller wheels. so on city driving you'll find it that thers a little higher rpm to move from stand still compare to the previous wheels.

did you maintain 10km/l FC while wearing those 19" shoes o after mu magpalit?

aftermarket or "racing" filters can provide better FC versus stock but with the right driving attitude and behavior of the driver itself. why? eh kung galit ka ba naman sa pagtapak sa gas pedal, e malamang malasing mu makina mu at parang umiihi lang ng gasolina eh.

di porket nagpalit ka ng free flow intake eh mas matipid na, depende pa rin yan sa nagmamaneho.

Moderate naman yung tapak ko sa gas,i always maintain 2k rpm before shifting gears. Minsan lang sa 3k,usually sa 1st and 2nd gear lang ako umaabot sa 3k rpm.

Since upgrading with 19s my Fc went down to 9km/lit.then after the knn now its down to 8.something... Nung pagka kabit na pagka kabit nung knn ramdam ko talaga ung nadagdag na power. Pero ngaun,its been 2weeks parang feeling ko hindi ko na maramdaman ung nafeel ko na improvement nung bagong kabit sya... Hindi ko sure kung baka na imune lang ako sa performance na with the knn or baka meron talaga akong kaylangan ipaayos or ibalik nalang either ung stock filter or pati na ung sparkplugs...
