went down the bypass one day and i noticed my speedo and rev counter would go up and down when i went over 3000 rpm, now it does it every time i go over 3000 rpm. i want to ask because last time it did this the car wouldnt start. its a mk2 ph1, not really messed around with it electrically, excpet headunit, sub, all speakers upgraded and dashboard conversion.
any help would be appreciated.
