Hi ya guys, just looking for a bit of help. My radio is making a buzzin noise, wen i rev the car the buzzin goes higher as the revs get higher. Plus at the same time this started so did the speedo, it bounces up and down. If im doing 30mph the speedo says 60mph. Has any 1 come accross this problem? Thx Lee

 

Definitely seems *like* a wiring issue, for the radio it seems anyway. Since the speedo is also affected I have no idea on how to fix it. Perhaps others members might have some solutions.

did you change the spark plugs? old spark plugs without the R used to cause this....
