Crankcase pressure

[race7820000]

I have put about 150 miles on truck. Runs great. Other than a small minor flutter that starts around 1100 rpm. Like an injector is acting up. I put it on computer and did the 4 cyl cut out test and it said number 3 was not ok. Did one by one and nunber 3 sounded like it was cutting out then the other times like it didnt make a difference.

Number 3 doesnt fail the test everytime. I did it 5 times and it failed twice.

When ur pulling it seems fine. All kinds of power. No blowby. Not yet anyways. Doesnt roll coal. Burns nice and clean.

I didn't put any program in or anything, I figured leaving it stock would last me longer and I dont need to show off. Not for 20k lol

Anyways, the injector has a selnoid , the cat program has a test for it and it passed.

Does anyone know a different way to figure out if it is injector? I already put the trim codes off new injectors in the ecm.
I just want it perfect
Thanks
