Type your message normally. Avoid text speak.

Have a proper tune up. Check and adjust properly the ignition timing. Maybe replace spark plug. Set air fuel mixture properly.

Use higher octane gasoline.

cguro baka kelangan ng ipa-tune up yan kelangan lang i adjust sa tamang timing ang ignition nyan

saka ipa check mo ang intake at exhaust manifold gasket mo baka may sira na kasi kapag may sira na ang mga yan nag baback fire din

Another cause would be a leak along the exhaust pipe.

sorry po di ko alam na bawal pala text format..


anyways..nakapag pa tune up na po ako..siguro pacheck ko na nga lang po exhaust pipings or ung manifold...thanks po...

If you have an open exhaust, that's normal. If it's a stock exhaust, then you're probably running too rich.

[chielout]

ser paano po na open exhaust?

custom headers pipings and muff na po...normal lang po yun?

[niky]

Yup. That's it. If you have no more catalytic converter and your muffler is straight-through, backfiring can occur because the SiR's fuel programming is a bit rich. That's probably normal. Even so, check for unusual noises at the engine, check your sparkplugs (they should be reddish or blackish... not white or wet) and have someone check your timing.

Set your fix or base timing you would have to short the 2-PIN SCC (service check connector) located at passenger side right kick panel. It will assure that your ECU timing is starting from base calculation. Spark advance will adjust properly if ECU base timing is set correctly. for further assistance, jemsonabrigo*yahoo.com or jemsonabrigo*gmail.com Regards
