    roughly correct but your nose is not precise enough to measure how lean or rich your air-fuel mix is.


    Actually, it only happened with the Bosch regular temp platinum plugs. Never with the other plugs. The sound would be only single pops. It sounds more like a 'triangulo' and it happened twice yesterday while accelerating along SLEX.

    Been driving car the whole day yesterday. No problems until I was on my way home. The only thing I can think of is that the car has been in use for 2+ hours.
    Might be your engine is running lean causing a hot spot to happen resulting in pre-ignition. Adjusting for more fuel flow should correct the problem.

    Any idea (DIY method) on how to set the correct air-fuel mix for LPG ?

    why not just look for a Auto-LPG station that offers "free" LPG tuning if you buy fuel from them?

    CLEANFUEL (shaw) offers this service.

    Right now i'm using the NGK BKR GAS which is designed for LPG and CNG vehicles.

    Its running well with FC still consistent when i was using BKR6E-GPs however i noticed the car hard starts when i run it on gasoline for extended periods.

    Saw NGK BKR7E's (two step colder than stock) so i'll try these out just as well on my next plug change.
