many buses start "rotting" in terms of performance thru d years... any1 has a bus tt u lyk tts prob old and still in good condition
For me its 301H but it seems to be failing when it transferred to slbp from bram on sv.105 due to the NEL shift of bram and hgndep switch of control over eunos and serangoon int... basically i think slbp modifies the engine and original engine noises are rare esp d MB0305. 301H still has not been modified or broken down before well at least in my observation
