Hi , I have a 1999 Triton ute HK ,3ltr V6 Petrol , auto. After a long drive 100k + the motor runs fine , until i stop the motor for about 10-15min, then it starts to miss and stall when driving around the city , once back on the open highway , it usually clears itself , and a way we go. Had it put on the dyno maching , came up number 3 coil , changed coils , no change , still showed number 3 coil , another test , came up air flow monitor on turbo , changed monitor , no change , next we changed the electronic distributor (little black box before the coils ) still no change. Also change both fuel filters . Have had this miss for about 12mths now , and 100 mechanics can not tell me what is wrong . Please help Mark
