[QUOTE="RossKean, post: 1471855, member: 19880"] For the hard starting problem when hot, does the engine turn over at normal speed or is it sluggish. If slow to turn over, it may be either the starter or battery. Best check is to use a clamp-on DC ammeter to check starting current. If excessive (i.e. over 100A), the starter motor may be failing. If it is turning at normal speed, I wouldn't suspect starter or battery. I can't help you with the diagnosis code issues - I have a Gen II which is different. Sometimes a random code may be generated when you have a failed start so these might not mean anything. Still should investigate. I doubt it has anything to do with throttle body sync. [/QUOTE]
