I bought a 93 CX civic hatchback, and have had a speedometer problem right from day one. It jumps around, goes to zero at somepoints and stays there for a little while. and when it decides to work it only goes up to 40km/h when your doing 50-55km/h or only says 60km/h when your travaling 90-100k/h. Ive changed the speedometer sensor once and the gauge cluster twice. secondly the oil pressure light. it comes on every time the brakes are pressesd. sitting at a traffic light holding the brake slightly it will faintly flicker. what could this be? a crossed wire? any help would be appreciated. thanks

 

For your speedometer problem check your speed sensor
