mitsubishi "check engine" light

**laurence** · March 9th, 2005 01:08 PM

maraming salamat sa lahat ng nag-respond.

here's what's been done so far.

first i had the oil changed dahil akala may kinalaman sa maduming oil besides due na rin talaga for oil change. kaso hindi rin nagbago.

then i went to a motor shop at timog. they said kailangan lang palitan ang spark plug. again walang nagbago.

i then decided to go to mitusbishi along quezon avenue. they did a check up (at least that's what they told me). after the check up they told me na wala naman daw problem sa computer box and servo. now here's the disappointing part. when they returned the car to me napansin ko na umingay ang makina. it turned out na nagmula sa timing belt or tensioner yung ingay. nag-reklamo ako na walang ingay na ganun yung auto. but they insisted na dati na yun. anyway, wala ring nangyari kasi hindi rin nawala ang check engine light at pagsinok. tungkol sa sinasabi niyong error code; that's the problem wala silang sinabi kasi ayos nga daw ang comp box at servo. sa totoo lang nakakaduda nga actuation nung service personnel. also ipinagmalaki pa niya sa akin na pinalakas na nila power nung auto. oo nga lumakas but only because ginawa nilang 1.5 ang idling.
lesson to self: wag na babalik sa casa dahil in the first place di mo makita ang ginagawa sa kotse mo.

back to the topic: the following day i went to another motor shop para ipaayos na ang timing belt. sinabay na rin dito ang paghanap nga sa cause ng check engine. talagang hirap sila. eventually, na-discover ng mekaniko na mali daw ikinabit na spark plug dahil pang kotseng may carburador daw iyon. so again gastos ulit palit ng spark plug. he assured me na mawawala na ang check engine.

unfortunately... hindi nawala.

i'm now thinking of having my fuel filter replaced. i will take into consideration all your comments they are really helpful. talagang napaka-expensive na problem pala nitong check engine na ito.

may alam ba kayong motor shop na capabale na ma-check ang computer box?

change fuel filter ka rin...

sorry mahina ako sa mga technical terms sa kotse.

what is MAF sensor and where is it exactly? also how do you clean it?
ano rin yung a/f mixture?

Laurence,

try checking your battery connections.

This happened to me before, umiilaw bigla yung "Check Engine", lalong lalo na pag nag flash ako ng high beam... kala ko may grounded sa headlight ko...

tawag ako kay raymond sarrol, sabi niya check ko nga daw yung battery terminals... sabi ko nde siguro yun ang problema kasi na-check ko na yun eh...

the next morning, naisipan kong tignan ulit yung terminals... nde naman gumagalaw... so ginawa ko pinihit ko ng malakas... ayun gumalaw... hinigpitan ko and hindi na nag "Check Engine" ever since... not even once.

Hope this helps

by the way, we have the same car... 1993 model lang nga yung sa akin

ang fuel filter (kung replacement at hindi orig) pinapalitan every 10K.

ang MAF sensor... sensor yung na naka kabit sa air intake tube ng sasakyan.

pagawa mo sa mekaniko kung hindi mo alam... mahirap na at baka kung ano pa ang masira.

thank you. ang hirap lang talaga maghanap ng magaling at honest na mekaniko. yung isa pinakialaman pa yung clutch ko na hindi naman dapat. napansin ko na lang na lumalim sa apak. the following day tinanong ko bakit inaudjust niya clutch tumawa tawa lang.

sa akin baliktad. nauna pag-palya bago labas check engine. pero pareho lang siguro yun. hindi naman namamatay basta minsan ganda takbo tapos bigla na lang nabubulunan. ano suggestion mo gawin sa fuel pump.
