My 05 has rough idle on start up sometimes and the dealer put two new injectors in it and when I cranked it up to leave the dealership it did it again!!
I was in too much of a hurry and did not complain. It does it from time to time only on start up and I cannot find any pattern for it. Sometimes it does it after sitting for a day or two. Other times it does it when I just stop for a fill up. It only lasts for about less than 30 seconds. Then it smooths out and runs fine. Good power, good fuel economy. I hate to sit around the dealership waiting for service so I have been living with it now for 3 months. Never seems to get worse. Is it really the nature of this beast??
I would think it has something to do with an injector leaking. Any ideas??
