To those with idling problems...here's how I solved mine...

Kung permanently on ang aux fan, you're engine might be running too cold. Which is nearly as bad as running too hot.

0loap/hbk: I had it done at Tower of David sampaloc (cor. espana and maceda sts.) Then name of the mechanic was Ambet. Actually, I was looking for my regular mechanic, Neil, kaso he wasn't around coz it was a Sunday and this was the first time I saw Ambet. Siguro he was a pullout from another branch. Well, I guess it was just my day because he solved my problem.

Yup, my auxillary fan is connected to my a/c compressor so that it just turns on whenever my compressor is on. But my radiator fan is a different story. Originally, belt-driven ang radiator fan ng Vitara. We converted it to an electric fan type with switch so that I could manually turn it on or off during deep water fordings. The radiator fan was connected also to an independent thermostat that automatically turned the radiator fan on or off depending on the water temperature. However, nasira itong custom thermostat around May 2003. I wasn't able to find another thermostat like it so I made the fan permanently on full-time but still retaining the manual switch. I think it was somewhere during this time that my original idling problem came about.

Hi! Pasensia na kayo...ano kaya problema ng Mitsubishi Galant 1992 Automatic Transmission MPI ko...Kapag walang aircon medyo O.k. pag shift ko sa drive medyo lang nanginginig...pero kapag naka aircon na baba ng konti ang idling...kapag shift ko na sa reverse or drive sobrang bumababa ang idling...grabe ang kinig..parang kapos na kapos ...2 yrs ko ng problema...pls. help me...

gorio, it's very likely the idle air control valve or servo of your galant engine is busted. sakit yan ng lahat ng 6G and 7G galant (up to 1997 or so) and lahat ng lancer. maraming mapapag-ayusan niyan.

try mo muna tanggalin yung negative terminal ng batt for awhile or check bore trottle baka ma dirt&grime lang try to clean it..or else servo nga..na s stockup yung solinoid nya kaya endi na makacompensate sa ecu..

[finchy18]

nice treat.

[gorio31]

idle air control valve or servo ...baka pwede paki sabi kung saan parte to ng makina...pasencia na wala ko alam sa makina...dami ng mekaniko ang parang nangloloko sa akin...saka ano yung or saan ko makikita yung bore trottle ....ty. patulong uli ok..

[JAYarc]

bore trottle yun connection ng gas pedal sundin mo yung cable, connected din sa dulo ng airfilter intake connection..alisin mo yung hose at makikita mo yung batterply na nag ko control ng intake a/f mix yung pagitan madalas ma grasa yun linisan using lint free cloth etc..yung servo nasa bandang baba lang ng trottle assembly madalas black sya na may wiring connection..minsan tinatangal yun baka may humarang na particle(sand alike)..na makaka effect na idle pero madalas defect eh stockup yung solinoid sa loob ng servo ..happi DIY

Question:

Does anyone know what the "water temperature sensor" is for?

I know it is different from the "temperature gauge sending unit" and "temperature switch", but I do not know what it is for...
