MAF or Servo

[fernalob]

MODEL: Galant (7th Gen, Manual, ECI-Multi)
PROBLEM: Slow Engine Response/Jerking/Choking

Pag Start: namamatay pag 'di lagyan ng diin yung gas para i-start yung makina. kahit buksan ko agad aircon namamatay parin.. dapat pag start naka diin ka sa gas ng konti ng mga 3-5 minutes para hindi mamatay ulet.

Pag naka Neutral: namamatay makina pag biglang apak sa gas para mag rev. nasa sahig na apak mo di pa umaabot ng 3k yung rev and parang umu-ubo ubo pa yung makina then mamamatay.. Dapat apak apakan ng dahan dahan para umangat yung RPM.

Habang nananakbo: kapag nagShift ako to another gear (higher or lower) dapat dahan dahan ko apakan gas or itaas muna rev ko para umandar at di mamatay makina.

sabi ng mga tumingin, may nakakabit daw na 'idle up' daw yun, pero pwede daw tanggalin.

tsaka nga pala, nagsimula nga pala ito nung pinihit nung may pumihit sa inaakala nilang idle control mataas daw kasi menor. nung nakuha ko toh mejo okay naman eh, may kalampag nga lang pag nasa high gear na, 'tune up' lang daw yun..

naghahanap lang po ng madami pang advice (habang nag iipon ng pampagawa) kasi may nagsabi MAF meron naman Servo

thanks po.

Sir i adjust mo muna yung idle screw. Located ito sa bandang likod ng throttle body. Kung ito yung pinihit malamang sumobra ang baba ng menor mo kaya namamatay ang makina, iset mo ito sa 800-900 RPM. Yung idle-up naman eto yung para sa adjustment ng menor mo kapag naka-aircon ka. Dapat 1000 RPM ka kapag on ang aircon mo. HTH :D

Base Idle Set Screw or BISS

The Base Idle Set Screw (BISS) is located on top of the throttle body, covered by a soft seal. But it's not just any screw. The BISS controls a throttle body air bypass that allows the adjustment of the idle. If your car is not idling right, it may be because the BISS has fallen out completely. The average Mitsubishi dealer seems to have no idea what this part is; we've heard of parts counter people claiming you have to buy a whole new throttle body to get the BISS.

The BISS, whatever, is adjusted to compensate for the A/C compressor load. So the engine should have reached normal running
temperature and the A/C compressor is engaged, then Adjust the BISS for 700 to 800 RPM while the A/C is running. Idle RPM should not change much when the A/C compressor solenoid disengaged.
Hope you get your RPM back to normal and Hope I have it right.
