So my truck was sitting for a few months because of two bad injectors. I finally was able to replace them but now when I reach 35mph it starts to shudder as I maintain speed or give it has normally. If I stomp on it it seems to work just fine. I'm at a loss. A friend told me its probably just air in the system and I just need to keep driving it but I've already driven 50+ miles since but it still does it.
Any ideas on where to look?
