Long story short. Went on holiday drove over 1000miles, started ticking, hardly any oil so added more. Car started smoking and no power and misfirering. Garage said to much oil and changed start plugs. Drove a further 200 miles and started misfiring again. Replaced ht leads but may be faulty as still misfiring. Guy in garage on holiday so young lad looked at it. Not sure if he has put my ht cables back on in the wrong order. So don't know what to do. Any ideas what order the attatched to the rotar arm cover and if not the ht leads what it can be? Cheers
