Hi guys may idea kayo kasi nanginginig yung Fx namin after ipa tuneup. Pinalitan is spark plug contact point condenser, change oil and oil filter, air filter. After nun lalo nagkaproblema ata yung makina ng kotse.... San po ba pwede pagawa yung ganun? And may idea po ba kayo kng ano mga cause neto? Dati bago pa tuneup mas ok pa eh. Yun lng medyo matagal na di na tuneup kasi yun.
