Need help ASAP again :/

I noticed my truck runs a little rough before it gets up to 180* ect and 188* eot. I have no codes checked it twice. My edge cts shows no codes either. Good ficm 48.5-47.5 all day long. It seems to be bucking. I just changed fuel filters and it didn't help. It don't seem to be getting any worse it's just annoying. Once it's up to 180-188 I can run a 1/4 in 14.4sec. I don't know what to look for next. Working on buying a new house I really don't want a big problem cutting into my downpayment funds.

EBP sensor, EGR, ICP sensor especially if early build...

The list goes on and on. You need to monitor some data to be sure.

See what ICP EBP BARO MAP are reading key on engine off.

I agree with sinner6.0. Get it scanned; you will probably find you need a new injector.

Spool valves in the injectors are sticking.

Scanned means with a contribution/balance test or maybe just a simple injector buzz test followed up to confirm with the C/B test will find the culprit cylinder. Stiction does not show as a code unless it is real bad. Doing it cold is usually the best time to catch it.
