No fault codes and I don't see any leaking.
Don't know how I could check for air being sucked in.
It's running better every day, though....maybe it needed to recalibrate itself?
And yes, I have an AE scanner....what should I be seeing on the ICP? I can log ICP over a period of time and then look at it as a list of saved values or a graph.
I am leaning towards having an issue with low oil pressure, either because of a leak at a stand-pipe, end plug or STP fitting.
Another possibility is that I'm losing fuel past my injector o-rings.
I lean in this direction, since I installed a GDS fuel pressure spring last year and was running it up until I started getting long starts this past November.
I have since replaced the spring with the Ford Blue one, however, I could still have a fuel leak past the o-rings.
I just received my stand-pipe and end plug kit from Tousley Ford last night and I have a full set of injector o-rings which I will likely install all at once.
Do you have a recommendation on this? It seems like the stand-pipe and end plugs are fairly easy to do so I will do them for sure, but, not sure whether doing the injector o-rings at the same time is going to help me figure out which one it was.
