Hi, I having issues with my mk3 golf vr6, when I start the car up in the mornings, or some times throughout the day it will reset all my clocks and struggle to start, it always start but seems to struggle but also it has and idle issue where the revs will sit at 1000rpm instead of 750-800 rpm, it's had all service parts, all earth's checked and replaced where needed new battery, new alternator, new starter motor, coolant temp sensor any one have any ideas? thanks Keaton
