Stumble/Miss/Hesitation

I got a gryphon in early sept and have the EXACT same issue. i thought it was coincidence, but it only does it on SETTING 2 / 87 economy tow. Drivability is crap. I had to turn it to setting 1 'tow only' or 'shift only' or whatever its called.

at this point it looks like this is a known issue with the canned #2 tune, not a couple coincidences. Good thing I found this, I was just about to start throwing parts like coilpacks at it to solve the issue.

I guess its time for a ticket for me then. btw...2006 fx4. is it just me or is this a lot of 06 models?

I think I may have this same problem as well. Mine is not that frequent. Maybe once a month. But it will run rough just like it is missing and then all of a sudden clear up. I have the 87 performance tune on an 2007 5.4 about 61,000 miles. I guess I will put in a ticket as well.

I have an 06 aswell. But I am getting the problem on all settings. I seem to get it more often in towing and performance setting then economy so I just leave it there and deal with it. However when you have an 8 foot camper on your truck and your climbing 2 miles of 12% grade and the problem happens you pretty much have to pull over. I have noticed that if you turn the engine off and start it back up, it (the problem) instantly goes away.

I'm going to correct own post here..mine is actually a 2007 not an 06. Not sure what I was thinking when I typed that.

Hopefully this gets resolved soon. I'm back to level1 - tow only until then.

It would be much appreciatived by the staff at PHP if you would ALSO fill out your info in your User CP.....
Just your name doesn't cut it......
They need your phone #.....
Vehicle info.....
HEX code......

It's just a good thing to do.

Thank-you

I do realize that, but this forum is a secondary source for contact info for PHP.....

I know it may be a PIA to do but I was just asking if you could complete it.....no one else will be able to see or use the info except PHP.

Thank-you

My calibration update was received and has been installed. We'll see how things go. Thanks to everyone (especially Bill) for working towards resolving this.

If there is an update for this how will I know? I have a ticket in but have not heard anything there. Will an email be sent if my calibration has an update or do I have to keep checking the ticket and this forum?
