Idling goes down from 800 to 500 RPM...

**hyperthread** · May 6th, 2007 11:30 PM

Hello Tulong po,

Whenever I hear the usual heavy "tik" sound (indication of one of the fans turning on; A/C returning from thermostat) my RPM (while gear is at "D") goes down from 800rpm to around 350-500rpm and usually lasts half a second. When it does that, the thing shakes violently a bit.

Ano po kayang cause and fix dito? Lately ko lang naexperience ang problem na ito eh.

Thanks!

ganyan nangyari sa Lancer GTi namin dati. Check ng Mitsu tehcnician ang servo kit, throttle body & ecu. Servo kit ata pinalitan dun sa amin.

More than likely that it's just an issue of tuning. Either way, it's nothing to worry about.

same thing happen to my ESI bagsak RPM pag ON ang AC init sa traffic. ung IDLE UP ang problema. convert nya ng TOYOTA(big body) IDLE UP 450pesos lang compared to HONDA libo and so far ok naman. Madami na akong nakitang ganoon ang ginawa nya di ko lang alam kung pwede sa car mo. mukha nga lang naBYPASS operation na engine ko kci dami tube na ginamit per ganda naman tignan kung maayos ang gawa.

try mo idle up..pag di kaya sa idle up..check mo servo kit,dont buy a new one. linisin lang with carb cleaner. ipagawa mo sa marunong. usually dun ang sira "madumi". pag nalinis mo na at ganun p rin. well probably ung computer box n. wag naman sna.

Nangyari po pala ito one very hot saturday afternoon. So ang ipapatsek ko po sa Exalta STA ko po ay:

1. Idle Up (para saan po ito?)
2. Servo Kit (kung servo kit di ba po lagi ako mamatayan na nun?)
3. Actuator (Aircon related?)

Napansin ko din na nagti-Tik yung aircon ko pero the fan doesn't die down.
Ang ibig sabihin po ba nito ay nakarekta ang fan ko? Di ba po namamatay din ang fan? Or hindi sya mamatay pag mainit ang panahon?

At saka parang may sipa pag umarangkada so feel ko yung pag engage nung compressor? What do you think po?

Attachment 8046
ito po ung DENSO IDLE UP ng toyota, sencya na medyo madumi engine bay kci galing biyahe. KHAOS disable ko muna kci pagawa pa ako ng T-connector...medyo ok din po kci from subic to hundred island via Zambales almost 400kms round trip 1200 ang gas(34.95/ltr)ko.

Attachment 8045
eto po ung connection nya. ung positive is connected to the compressor relay then negative sa body. kinulang ako ng T-connector and tube kya ung tube galing sa cylinder head to air filter wla.

HYPER: as per my mechanic, IDLE UP controls your IDLE so your RPM will go back to normal 700-800 pag open AC. and about the tik sound po it means nag OFF or ON po ung compressor. ung akin direct ung FAN ko so hindi cya namamatay pag nag-off compressor. di pa po ako OH eversince and never get to 1/2 ung temp ko.

mga sir, based lang po ito sa experience ko....
