siguro bro, the best nyan is to have it scanned first, para matumbok ang sira.... para di ka na din magastusan na kung ano ano ang pinalitang pyesa pero hindi pala dun. pag scanned, direct to the point and diagnosis and parts replacement ay one hit.

cannot recommend a shop in muntinlupa, but kung kakayanin, i am recommending servitek alabang (in front of toyota alabang). may scanner sila dun.
