Stumble/Miss/Hesitation
 
Has anyone experienced a stumble/miss/hesitation with their Gryphon. Occasionally, I can just be driving down the road and get a terrible feeling. Its like I have a coil pack out or something. There is no rhyme or reason as to what sets it off, it just does it and the only thing that fixes it is pulling over and turning the truck off and restarting. :cursin:

I tried setting the truck back to stock and ran it that way for several weeks and everything was fine. This usually happens at least once a week with the programmer on the truck.

Any ideas?!?!

2006 5.4

No ideas at all, but the fact that it runs fine at stock makes me suspect the tune, as I'm sure you do. I think Bill is going to have to be the one to fix this.

I thought I had heard of someones acting similar before but could not find the post. Maybe it was the torque converter "shuttering" that I am thinking of. I am not sure if it is the same thing or not. It really feels like a coil pack is unplugged. I have tried to contact PHP by phone several times regarding the issue but have not had any luck. Hopefully Bill will see this post.... Bill?? :shrug:

There have been some cases of part throttle suddering of the torque convertor engaugement while going back up a hill after coming down from one.
Mine was from using coast button on the cruise control.
How many miles on the truck?

69,xxx

It seems like it may always start with a coast and part throttle type driving. It did it again today and I let off the gas and got back in it and it went away. I was kind of excluding the torque converter as before even making it downshift would not make it go away. Only turning the truck on and then back off would.

Keep the ideas coming..... Can a mod point Bill to this thread?

I know they are busy but any idea the best way to get a hold of them?

88Racing Wed, March 31st, 2010 06:13 PM
Yes they are awfully busy!!!!!!
Try and call them and not just once or twice. Try a lot.
Or fax them a note.
