Rough Idle

[jmocelts22]

I have a 2008 w/ a 5.4 and an edge evo that i run on level 2. I have noticed that the truck will have a slight shake to it when idling that it did not have before. I am not sure if there is a setting that can help this or if it is just the nature of the beast. I just want to make sure nothing is wrong.
Thanks

I've never noticed anything like this in my truck. Does the shake go away if your set the tune level to stock or Level 1?

You COULD be experiencing an effect of a dirty MAF, but I really wouldn't expect this in a 2008 truck.

Mine is a 4.6 and does the same thing but always has. You could try fixing it by raising the idle speed a little bit.

How long have you had the edge?
Are you running a cold air intake?
How many miles on the truck?

I have had the edge for about two weeks. I pretty much run it on level 2 all the time and i never noticed it on stock. I have done a Gotts mod w/ an AEM dry flow filter and magnaflow muffler. I only have 17,500 miles on the truck.

I dont think it is a big deal but it just runs soooo much different than it did stock that I dont know hos it should run. When it idles down it is arond 600 rpms. It feels like it has a slight lag when driving @ slow speeds sometimes like it loses power for a split second. @ WOT it seems to run strong.

Like Longshot said you may want to bump the idle up.
Right now the new program that you loaded is making the trucks computer relearn and that could ne causing the low idle.

Since I have been experiencing the same issue, I have noticed that most of the rough idle issues myself and others seem to be experienced on level 2. Maybe the level 2 tune needs to checked out. Unfortunately, it is an intermittent issue and may be difficult to target to reason.

Are you referring to edges canned tunes, Gryphon canned tunes or custom tunes?

[lbjailer]

I am using a Gryphon with custom tunes, a converted Edge.

Posted a note for PHP about your problem.

My truck seems to have developed a similar issue as well. When it sits idle for a few seconds, it drops and "shakes" ever so slightly and then idles back up. This just started a week or 2 ago. :hmmm:

Rob, Clean your MassAirFlow Sensor first. I konw you're dumping a oil/gauze filter and that could be the problem. The oil will dirty up the MAF and cause rough idle issues. If that doesn't fix it dig deeper.

It's gone. Just eventually went away. :shrug:

Check the other thread. Posted the MAF cleaning link.

Take off your throttle body ( four bolts) and clean it out you'd be suprised how dirty it gets, clean it with some carb cleaner and some rags, and also while your at it take some brake cleaner(electrical cleaner) to your maf sensor ,thats it let it all dry , reset your pcm with a tune, and you should be good

Watch what fluids you suggest to clean the TB with some of them may not be O2 senser safe...

I used the stuff from napa auto -intake medic-haven't had any problems in years.

The biggest concern is not so much what you use, but that you either remove the throttle body before you clean it or use a rag sprayed with cleaning solvent to clean the throttle body. What you DO NOT want to do is spray solvent down the intake. Most of the manifolds are plastic nowadays and the solvent will not be very friendly. :yikes2:
