I have a strange problem which is probably easy to diagnose but difficult to find. My 1997 Plus 8 drives like a dream until I switch my sidelights on. Various things happen, but the worst are:
1) The engine starts to miss when under load - this never happens otherwise
2) The fuel guage reads about a sixth of a tank higher
3) The speedometer goes wild, either:
a) if I am stationary it sometimes shoots to about 80mph then back to zero and stops working. I need to restart the car to fix this.
b) if I am driving it appears to add approximately 10-15 mph onto my speed (but can go higher) and wanders even if I am holding a constant speed
None of this seems to happen when I have my headlights on... which is strange because aren't my sidelights still on???
Any thoughts? I guess I have a short somewhere, but how do you start looking?
