No reason to reach operating temps with warm up. At 68F OAT, I typically warm up fpr about 30-60 seconds. The shuttering you experience is likely some other issue.at 0530 and 68F OAT i still experienced some shuttering after a 5 minute warmup. what do you suppose ought to be a normal warm up period of time for this diesel? i will continue to extend my warmup time until operating temps are reached. however, being new to diesel i desire a better understanding of operating cycles. with these warm temps i hope to be prepared for winter cautions. anyone with advise please advise. thanks
