P0272 Code

[usctrack]

All,
I am getting a P0272 code. My truck has had a cold starting problem for years and lately it is stumbling pretty bad until it gets warm. Then under a load you can still feel it some.

I have a CCSB with SCT and EDge INsight monitor as of a few days ago. Monitor shows FICM at 48.0-48.5.

I am also running Hot Shot Secret with hopes that this is stiction. So far it hasnt cleared it up. I am not running synthetic but will on next change and all others after that from the info I have learned on here.

So what I am trying to find out it, is there any way to determine if the code is -
1) stiction
2) FICM
3) Injector

Thanks all.

It's not stiction, still could be ficm. I would do this.......Ohm tested #4 injector.

What year is your truck?

I have some diesel kleen with cetene booster and will add it ASAP. I picked it up last week and just haven't put it in yet.

I am going to ohm test the injector. Not sure how to do it and where to start but ill did into the threads and see what I can find. Do you know if I have to remove anything to get to the injector? I haven't some much wrenching on her yet so I assume I'm about to get dirty.

While I run diesel kleen your issue is likely on the oil side not fuel side

[usctrack]

I was thinking that too and tried the HSS. Looking at rev-x but not sure If i can run both in there or have to wait for next oil change.

All you have to do is squeeze the wire retainer to get the harness plug off. It doesn't take long to check, it could be a mechanical failure also.
