    Good day Tsikoteers! Tanong ko lang kung ano kaya ang problema kapag palyado ang andar ng makina sa unang start sa umaga? 2002 Honda civic AT po ang sasakyan at hindi naman malamig ang panahon ngayon ngunit parang nabubulunan siya, pero agad itong nawawala pag nirebolusyon ang makina. Bagong change oil at air filter naman ito. Napalitan na din ang timing belt. Ang nabago lang ay nagpalit ako ng magnetic clutch sa aircon. Salamat

    pag malamig ba nangangamoy gasolina ang exxhaust? pwedeng me problema ang coolant sensor but you need a scanner to verify the reading.

    t2erns, di ba talaga namang amoy gasolina ang exhaust?

    when you say scanner, do you mean the computer analyzer? what has the coolant sensor got to do with smooth engine start?

    yun nga rin iniisip ko shadow, baka kailangan na i-adjust ang idling rev? sige check ko ang manual.

    hingi muna ko marami feedback dito bago pa check sa mekaniko, natitiis pa naman..

    baka lang kasi simtomas ito ng mas malaking problema later..

    thanks.

    when coolant sensor is bad normally it will read super cold, the computer will enrichen the mixture to achieve operating temperature at the least minimum time kaya the result ay rich mixture (mangngamoy hilaw na gasoline sa exhaust) at posibleng meron pang konting backfire at parang nasasakal ang engine. (the engine will operate on open loop longer and matagal bago mag closeloop)
    BTW sa scanner (some call it analyzer) mababasa mo ang mga readings ng mga sensors.

    Maybe something wrong with the idle-up (for cold starts)? In the case of my car, it was a faulty temp sensor that triggers the idle-up. Once it was replaced, back to normal.

    Salamat t2erns for taking time to explain, thanks also ghosthunter for your response. Come to think of it, amoy hilaw na gasolina nga lately ang exhuast fumes ko. So it seems that I should have my engine analyzed for sensor problems. I remember back 2008 that my TDC sensor failed and it cost me so much inconvenience since I had to have my car towed at EDSA, this aside from the repair cost and the cost of tickets to the Cris Cross concert at Araneta which I forego because I had to take an early bus back to the province being without a car. Nadala na kaya gusto ko na unahan ang problema hehe...

    Saan kaya maganda mag pa analyze sa Alabang area? Salamat po.

Palyado ang makina sa unang start sa umaga
