My crosswind's tachometer needle, sometimes it works sometimes not. Pang 3 days ng ganito. Minsan umaandar ako, gumagana siya, tapos bigla na lang pupunta sa zero 'yong needle. Try to rev the engine higher, pero ala response 'yong tachometer. Turn off engine, and re start engine, ayaw pa rin. Turn off engine and wait > 2 hours, ayon gagana na naman 'yong tachometer, after few kilometers, balik na naman sa zero 'yong tachometer needle.

I'm checking my oil level, and normal naman. Di rin lumalabas 'yong low oil pressure warning sa dashboard. Sino na nakaexperience ng ganito? Any idea what could be wrong?

Sirs advise naman jan, thanks.
