Mitsubishi Lancer GL 1997 - performance

[berniebok]

Mga sir hingi lang po ako ng advice sa lancer ko. Saan po ba makikita ang adjustment ng idle up sa carburetor? pag nka aircon po kc ako ang baba ng idle nya. (500 to 600 rpm)

hmm. . .so this means the idling is okay when A/C is off.

Try this:
1. The idling should increase when you turn on the A/C. The compressor consumes engine power necessitating idling increase.
2. The thermostat controls on/off of the magnetic clutch of the A/C compressor (you will hear it click). AND ALSO controls a small solenoid valve.
3. The magnetic clutch is okay because it lowered the engine rpm.
4. The small solenoid valve controls the vacuum. The source of this vacuum is also from the carburetor. We use this vacuum to assist other systems. In this case we use the vacuum to increase idling when your compressor activates.
5. Vacuum from carburetor connected by small hose to solenoid valve then connects out by a small hose again to a diaphragm.
6. This diaphragm is the one that increases idling by simulating as though you are stepping on the pedal.

Troubleshooting is by isolation.
1. Check your hoses first. Busted hose mean no vacuum transmission. Suck on the hose leading to the diaphragm. You would see the idling pulley move if okay.
2. Also check the other hose for leaks.
3. Check also the solenoid valve if it open to deliver the vacuum to the diaphragm.

If you still can't find the trouble then better call a qualified mechanic.

in our older (non-lancer) car, it was just a cylindrical item (the idle-up solenoid) attached to the outside of the carburator. the electrical wire was just disconnected. all we did was to connect it..

-------sir ang galing mo ahh, pwede ako naman magpatulong?
ayaw mag start ng lancer itlog ko GLXI 1995 model matic.
nagpalit na ako ng sparkplug at mga cables ,, nag sspark naman kapag ini start ko. Walang gas na sumasampa, pagpna primeranko ng kaunti rumeredondo pero ayaw magtuloy. Pinakikingan ko yung ejector wala ring click, yung fuel pump hindi ko rin naririning na gumagana pag nag ignition ako.

dko alam kung saan ang fuel pump relay nakalagay baka palagay ko putol mga linya kasi ilang buwan naka tigil ito. baka sinalbahe ng mga makukulit na daga.Pero hindi ako sure kung ano talaga problema.

In my case, my Mitsubishi lancer gli (4GI5 MULTI-ECI) decreases to a very low RPM after traveling several kilometers. After I turn off the engine and after few minutes turn it on again, the RPM is very low that the engine will die. What would be the problem and what would be the possible fix? Thank you.
