morning all wondered if anyone could shed some light on this problem. p38 4.0 thor engine. Start the car and its fine rev it and it ticks over at normal tickover speed drive it and it then ticks over between 1500 and 2000 rpm. Turn it off and start it again and tick over is back to normal. Ive checked the throttle cable and its not sticking any thoughts on potential problem. Cheers Jason
