hesitation
Bill,
I am not sure this is PHP related or a fuel issue. I have not driven my truck for about 3 weeks and did so today. Twice when I gave it more fuel it stuttered in the 30 to 35 PSI boost range. I am on the stock #2 setting for econ. Any thoughts would be great. I also just replaced filters about 2 weeks prior to parking it. |

It has not happened and quite frankly I am not sure if it is a stutter in the engine or tranny because it has only happened twice but it is definitely a power loss in one of the two. I have been meaning to give you guys a call and ask some questions including the tranny/engine tune combination but the holidays were here and I broke my ankle on top of it (why it has not been driven). Hope that helps and I look forward to any thoughts.

Well, I drove it a bit today and it did not do it again. I am wondering if was a fuel related issue. We had some nasty weather for the past few weeks so I am hoping that was it. I was going to try to call today but I got my hard cast off and was in too much pain to call when I got home. I also just noticed you guys are closed for calls on Fridays so I will have to try you in a few weeks when I get back from DC. I am still leaning that this is not a Gryphon issue but thought I would ask anyway

No worries. Sorry to hear about your foot. That's really gotta suck! :ouch: Hope they at least gave you some good meds.
Keep us up to date. If it does it again, let me know and I'll be happy to take a look at the situation. Rest easy and have a safe trip to DC.

yes they gave me great medication. I laughed when I saw the amount they gave me a week ago because i said to myself that there is no way I am going through 75 pills in a week. Well, I got my prescription refilled this morning.
I will call you in a few weeks and obviously if the stutter happens again. |

I am not sure how to answer this.
 I only have two choices, diesel and biodiesel, and I won't put biodiesel into my truck due to the warranty stuff. The hesitation was a glitch in the tranny programming which has been fixed. |
