guys,
nagpalagay ako ng brighter lights sa mga guages ko (speedometer, fuel, temp) sa liteace ko. now, nanginginig ang needle ng speedometer ko from 0-40kph. pero it's steady naman beyond 40kph.

ano kaya ang problem nito?

and my fuel guage is ok naman, pero once it reaches below the 1/4 mark, medyo mabilis magfluctuate (like when it's just below the 1/4mark when i start to use the van, maya-maya nasa near-empty na siya, tapos after a while napapansin ko na back to just-below-1/4.
