how can i fix my range rover 4.0 petrol auto?

Don't go any further,you have had problems since you replaced the HT leads,go back over them check 3x times they are RIGHT then look for another cause,stand back check methodically at how you have done the job and try again.Re-do your actions from the start Slowly and one bit at a time,at the very least you will be back at square 1 and can start again if you don't then you will spiral downwards.
