U0638

I've tried searching for this... I cant find anything with this code related to a powerstroke! Truck is an 04 extended cab 6.0 auto, 105k miles, bullydog triple downloader tuner, straight piped, also running a vegi-stroke. Other than that, truck is stock.

Its a can bus communication code. Most likely from that tuner.

Can you elaborate? Why would it come on now? They've had this tuner on for more than a year. They usually run it on a "medium" setting for mileage reasons and because driving it stock sucks. They know better than to crank it all the way up because the transmission wont work properly with it that high.

I'm sure the code wasn't there, he reads and clears codes almost daily.

The check engine light was on. Not sure if it was on for something else or for this. I know the EGR code comes up all the time now because we just did the EGR delete and the bullydog doesn't shut that code off. The truck is running great now. They just towed 10,000 lbs this past weekend and it didn't puke coolant once! They are still having a starting issue, where the glow plugs sound weak and it idles rough until it warms up, then runs fine.

6.0 doesnt give glow plug problems, sounds like the truck needs the latest reflash for cold start issues , for that , i doubt that code is why the light is on, sometimes tuner will set that code , egr is proably the reason for that , if its running fine , drive it

A truck that is running fine shouldn't be throwing CEL's every day though! We know why the EGR code is being thrown, he is looking at purchasing an SCT (like I told him to do a year ago) to get rid of that.

The truck just got a new FICM as well.

How can we tell if it has the latest flash or not? It didn't always have this issue, just more recently.

What do I tell him about the code then? It means nothing, just keep driving it? I'd like to think some day he can drive his 6.0 without having the CEL stare him in the face...

Thanks for the help so far guys.

fords ids scanner will tell in just a second if it has an update or not , i do agree that the truck shouldnt have a light ,but what i should have said was if he has plans on getting custom tunes with egr taken out then first get truck updated to latest calibration , if it just had a ficm replaced , it should have latest calibation , and he may actually have an injector goin bad and sticking cold,thats is probably his cold start problem, they can find that also on powr balance with ids when engine is cold if an injector is skipping cold or not, then once that is taken care of get the tunes and put in the truck , and see if light comes back on then, until egr is taken out of tuning i wouldnt waste alot of time on trying to fix anything , hope this makes a little more since, i can get into further detail, but woud rather disuss it by phone if so, pm me you number and i will call, its hard to explain alot of things on the net

Ok will do! Appreciate it!

Just got off the phone with him. He had the truck in the dealer again to assess the hard start rough idle issue. This dealer says injector #2 has an intermittent miss. Sounds like we should replace it. The last dealer told us 2,4,6,8 were bad, then we told them the FICM was, they replaced the FICM, truck ran great, but they still told us 2,4 were missing intermittently, now its just #2 I guess.... AHHH. I wish I had the tools some of the "diesel techs" in our local dealerships had, it would be so much easier! The tech even asked us questions about the EGR delete, he was amazed by it. He then went on to tell us he does more work on 6.4's now than 6.0's. ummm ok.

Ok so since my buddy and I are rather thick headed, we like to prove the issues out first, before just tossing money at the trucks. With MY SCT and the liveload software is there anyway we can monitor and see which injector if any is actually missing...? What parameters would we need to watch?

Thanks everyone for the help so far.

Scuffy, I'm shootin you a PM.
