hdi rev counter

[rd070707]

hi guys went to see an hdi that had two problems, the rev counter didnt move up for about 10-20 seconds after the car was started, then was normal from then on.

the speedo also just vibrated up and down quickly whilst the rev counter didnt work, then after the rev counter came to life the speedo was normal?

any ideas?

Check the dash earth in the footwell above the pedals.
