bitin sa hatak at medyo malakas sa gas

[ericty12682]

i hav a 97 model mitsu gsr... ok yung makina nung auto as in walng prob sa andar...bukod lang sa medyo malaks sa gas and parang nabibitinan ako sa hatak. nacompare ko kasi yung 99 honda vti ng bro ko,yung kanya mabilis pumapalo sa 3k/4k yung rpm nya compare sakin. cguro matter of 1/2 sec lang diff... here some of my questions mga broSana mabigyan nyo ako mga sagot pls.) Thank u very much
1. hindi kaya dahil mas matanda na yung auto ko kaya ganun nalang talaga fuel consmption nya? 8km/lit city driving...
2. Talaga bang hindi tinatiming ang mitsu GSR kasi may sensor na daw tlga? (newly change yung timng belt)
3. Ano ba dapat ang amoy ng usok ng isang magandang combustion na makina?
4. Given ba na mas malakas lang talaga hatak ng 99' VTI compare sa 97' 1.6 mitsu GSR?
5. hndi na kasi orig yung hitension wire ko,pwede kaya nandun yung prob kahit pa hndi naman palyado andar nung auto? Chinek ko yung sparkplugs ko(hndi black, hndi white ang kulay nung tip... its parang kalawang...) Is dat normal?
6. Ordinary lang yung air filter ko,bka nandun lang ang prob?
7. Or maybe nasa fuel filter? Ano mga symptoms na kaylangan na palitan yung fuel filter?

to answer:

1. afaik, 8 kpl is the average FC ng GSR on city driving.
2. yup, the timing is controlled by the ECU.
3. hmmm, that i don't know. hindi ko inaamoy ang usok ng oto ko eh.
4. may edge of power ang VTi kesa sa GSR.
5. nope, hindi dun. ano gamit mong spark plugs?
6. hindi din dun.
7. fuel filter should be replaced at least once a year.

bosch na iridium yung gamit kong spark plugs... so sa tingin mo bro walang bro yung auto...? tama lang ba yung 8km/lit na ratio? tnx sa sagot....

^ Don't be so surprised with the 97 Lancer GSR. Had the same car before and generally, your observations about the anemic engine and fuel consumption are spot on.

Dunno about the aftermarket parts you're using, but you could probably try switching back to OEM parts. When was the last time you had it serviced? The service advisor should be able to tell you if your spark plugs, fuel filter, etc. need replacement.

Well have it tuned at least at any Mitsu casa to find out the real cause. I have a cousin who has one. have the same FC problem for years and decided to convert it LPG. Ngayon umaga na wala pa panay ang pasyal eh.

dis jan lang napalitan lang timing belt nya ang nag pa change oil nadin ako... ang hndi lang napalitan is yung fuel filter,spark plugs and air filter. so do u think ok lang yung FC nung auto ko...?

[ericty12682]

also,nacompare ko din yung timing nung pag nag aauto matic yung aircon nung honda sa GSr. yung honda evry 15 secs umaandar yung aux fan,tapos mga 15 secs lang din sya namamatay. yung sa GSR naman mga 35 secs patay,35 secs din sya naka on... Ano yun...?

yes, tama lang. although, papalitan mo na din sya ng fuel filter and air filter. mura lang yun. for preventive maintenance purposes lang. dapat naman talaga pinapalitan yan regularly.

thermostat. i think its normal.

Kung aftermarket yung High Tension wires, you could try replacing them with original Mitsu parts. Some "performance" high tension wires have a propensity to crack, causing misfire. Depends on the brand, though... but the usual Chinese brands and even some cheap American ones are total crap.
