High Idle with Headlights On

[nowoolies]

my son`s car was doing the same thing
after going through half the car and electrical testing found the earth lead on the battery was the culprit
gave it a good scrub bit of anticorrision lube on the terminals and no more high reving dont understand why it worked that way but all good now

I'll try it - thanks. It is a reasonably new battery though (less than 5 months old), so it's a long shot, but I'll try anything!!
