June 22nd, 2011 09:59 AM #1good day po sa lahat.
may napansin po ako sa car ko... pag naka idle yung car at magtrip on yung a/c bumaba yung rpm ko sa 500-600 (normal idle rpm ko ay mga 850) at parang magshashake na ng kaunti. pero ang problem ko tuwing tumatakbo yung car. pagtrip on yung a/c habang tumatakbo yung car ang rpm ko ay bababa ng 500-600 at magstay doon ng mga 1-3sec at pag-accelerate ko medyo maghesitate ang takbo ko. kahit anong press ko sa gas ayaw tataas ng rpm ko. at after mga 2sec bigla na lang magshoot up ang rpm ko depende kung gaano kalakas ko inaapakan yung gas. ano po kayang problema nitong car ko?
TIA

that's how you do it. give as much information about your car and its symptoms to avoid scientific wild ass guesses. clean your throttle body and the idle air control with carburetor cleaner spray. at first start it will be a little bit more difficult to start than normal.

June 22nd, 2011 12:12 PM #5sorry po sa kakulangan ng info ko.
nalinis na po yung throttle body mga 2months ago. tried to do some research on the internet and found some similar problems about hesitation and they are suggesting cleaning the MAF sensor. could a dirty MAF sensor cause this intermittent hesitation during acceleration?

original pa ba ang set up ng ac system mo. the reason i asked, madami na ako nakita na conversion na ang pag operate the ac compressor. the ecu cannot sense the ac request signal kaya hindi ma anticipate ng ecu ang request para maadjust nya ang idling before switching on the ac compressor.

June 24th, 2011 07:54 PM #9papacheck ko ulit yung a/c ko. pero nong nagpalinis ako ng aircon system wala naman pong sinabi yung technician na conversion yung system ko. sa tingin ko lang po original pa yung system (tubes, compressor, condenser, evaporator) kasi wala po akong nakikita na medyo wala sa lugar at parang dinugtong lang (every week ko po inoopen yung hood para i.inspect yung nasa engine bay). pero just to make sure papacheck ko po ulit. di po kaya overcharged/overload yung freon ko? pero malamig din naman po ang buga ng hangin. di po ba pag overcharged/overload yung freon mainit din ang hangin ng aircon? pag nacheck ko na po yung aircon system try ko po yung ginawa ni bro earthlyken linisin ang throttle body. pero sa pagkakaalam ko nong nagpashop ako 2months ago nilinis "daw" nila yung throttle body. pero chicheck ko po ulit. salamat po sa advice niyo. update ko lang po kung ano sabi ng technician.
Puwede i try, 1. Palit air filter 2. Linis throttle body 3. Linis MAF sensor 4. Check spark...
high idle RPM at engine start
