is it a canned extreme tune?

 

Whens the last time you changed fuel filters, Oil change, Air filter change and is the EGR blocked off or full delete?

 

Try putting it back to your stock tune. If your lope goes away it narrows it down a bit.

 

Actually fuel filters are past due. I have them in my back seat, guess ill change them. I have an appointment to have oil changed today so that'll knock that out of equation. My air filter is afe stage 2 and not too old.

Thanks guys.

 

Does it smoke when this happens? Mine did an it was a injector miss firing.

 

Not sure. It always has a light haze smoke at idle when tuned.
Yes, canned tunes

 

get some customs tunes...........alot more refined

 

changed fuel filters, all is well!

 

I changed my fuel filters too recently because of the same issue. It didn't help my lope at idle though. I have no codes, but my truck also lopes at idle. When it is cold, I notice it more. But even when it is fully warmed up it fluctuates. Anyone know what causes this even when there are no codes stored? Could it be a sensor?? It does it running tunes, or when I set it to stock. It is more noticeable when it is tuned though.

 

good to hear!

 

My truck has been throwing a P2289 code for a while now and if I clear it the truck lopes at idle unless completely warmed up. I have no idea what it is but its going in soon to get looked at

 

How badly does your truck lope when you first start it? And how much do your RPM's fluctuate while it is loping? I have no codes though, may you have a different issue that's causing your lope..

 

Ill have to take a video of it but its a very noticeable lope, its not a slight lope at all. the RPMs jump from about 500 to 900

 

Mine is definitely not that bad! Mine is slight, but very noticeable still. I keep thinking that maybe my fuel pump is going bad.

 

Yeah my code is Injector control pressure too high- engine off.

It almost lopes as much as when I had the RCD 585 lope loaded on the truck

 

Ouch, that can't be good for it then
