This maybe asked before, but I'm new to the Powerstroke as this is my first Ford. It's 2005 F550 Super duty. Has 158210 miles on it. I got it at 156500. This issue was noticed about 7 days since I've been running it.

Idle is at 750rpm tach doesn't move but there is like a slight stubble every now and then
From about 750 to 1500 there is like. Slight surging (causes like a bouncing feel when accelerating) once gone it runs strong. No unusual smoking.

Noticed that it has green coolant in the reservoir and have had to top it up once. No visible leak and truck doesn't overheat.

I can still see the EGR on there.

No check light on
No white smoke.

Any ideas?

Also use Diesel Kleen cetane booster in it

P0272 is cylinder power balance fault. Don't know what p0299 is, not in my book. My book doesn't say what to do about p0272, just that it's cylinder 4. Can mean bad injector or weak cylinder. Compression test would be good. My old engine threw that code when a valve got stuck open. Didn't run rough at all
