May 7th, 2008 02:50 PM #1Kasi po sa umaga, syempre malamig yung makina, pag-start ko, tataas ng 2k rpm tapos kapag mainit na baba na sya ng 1.5k rpm... Ngayon ang problema taas baba na sya (from 1.5 to 2k rpm)
Nangyayari lang po ito during cold start. Magnonomorlaize lang sya after a few minutes na umaandar ako. Kapag mainit naman yung makina, wala naman akong problema.
Help po... Maraming salamat.

Again again? nabulol ako dun ah
Sounds normal to me, ganyan yan to quickly warm up the catalytic converter so it can perform its job. Kailangan mainit ang catalytic converter para efficient ang pagtanggal niya ng noxious emissions sa exhaust. It's just warming it up faster, plus it also warms up the engine faster at cold start so you can readily reach normal operating temp. Syempre pag mainit na, no need to do this so hindi siya nangyayari.
Baka gusto niyo rin banggitin kung anong modelo ng sasakyan, what year, etc so others can help you out sa susunod. Welcome aboard.

May 7th, 2008 07:16 PM #5cold start RPM at 2,000RPM i think is too HIGH... I have a 323 Mazda DOHC EFI Engine during cold start ang RPM lang eh around 1000 to 1,200 only but when warmed up RPM will go down to normal 800RPM to 900RPM.. masyado pabilis yun 2000 RPM and normal at 1,500RPM?? have your qualified mechanic check and diagnose your RPM readings
