03 blazer 4.3 fuel pressure
 

Hi guys, I just ran a fuel pressure test/leak down and was hoping I could get some thoughts on my readings.
This is what I got:

Key on @ 58 psi, after the key is on for 3 seconds it drops down to 53 and remains constent, no further drop

Idle @ 50

reving the engine @ 48~58

holding the throttle at 2k (the max it will go) @ 58

Then engine off @ 46 (will hold without loss)

These numbers seem kinda low to me, any thoughts?
Thank you

Keeping in mind we may have variation in gauge calibration I see no cause for concern. Is there a certain problem you're going after?

She's been spitting, sputtering and stuttering. I've had her for 5 years and there has always been an idle miss, recently it's been getting worse, now she's really carrying on when driving. I just started getting a solid ses light which is now blinking, it's coming up as a random misfire. I've changed the plugs, cap, rotor, fixed the vacuum leaks and checked the maf. Nothing seems to be making a difference. She seems to run fine cold, but after she gets up to temperature she throws a tantrum. Other than testing the fuel and knock sensor (which I haven't done yet) I'm at a loss.
