idling speed

[evo]

help nmn po... i just bought a 2nd hand '94 lancer glxi matic. napansin ko yung rpm nya ay bumababa masyado pag naka-on ung A/C then when i put it on Drive or Reverse. Minsan, namamatay pa nga yung makina pag reverse ko. When idle, rpm is about 900 then drops to about 200 or to a stop pag shift ko. ano po kya problema?

kung sa aircon lang nangyayari yan e baka sira na ang idle up servo kaya bumabagal. medyo mahal yan. pero as you said pati na pag shift mo in gear so...

pa-tune up mo. my best guess is that the spark advance is not set right, wala sa timing kaya pag nilagyan mo ng load e namamatay ang engine. dala mo sa mekaniko na may timing light para ma-set nya ang timing. pa-check mo din ang high tension wires to the spark plugs, saka spark plugs na din.

wala ba usok? kung may usok overhaul yan.

since it's a Lancer, most probably it's the servo.

I had that problem before and had my throttle body and servo cleaned and it went back to normal.

Kung after cleaning the throttle body eh ganun pa din, you have to get a new servo/servo kit.

yup, may konting usok pero every morning lng nmn pagka start. pero after a while nmn e wala na. how much ba inaabot ng overhauling and gaano katagal? may leak na rin kse yung cylinder gasket ko e... para sabay sabay na ang pa repair...
