So I just changed my own oil and when I started it for the first time it stumbled for a min..maybe the low pressure sensor? started but seemed to idle rougher? I let it run for about 3 mins and then I let it sit for 15mins and it stumbled again while starting? BTW the oil level is right and I used all Honda parts. Anyone else have this issue? The rough idle may just be in my head. It sound good up through the RPM range.
