I was told by Cody...
"Ok. The original poster's problem should be resolved. I will leave this thread open until I find out for sure. For anyone else that needs their calibrations looked at, please start a new thread as your problem may go unnoticed if you put it here."
So that is what i'm doing. I think I need my calibrations looked at, I have custom 87 tow tune, custom 87 performance tune, and custom 93 performance tune (my profile is up to date with my HEX code and serial #) In all 3 tunes, I'm experiencing the sputtering problem that seems to be going around. The truck runs perfect on the stock tune and on the canned tunes, it only sputters with the custom tunes. For reference,
this thread explains all the symptoms that I am experiencing to the tee. Before realizing that it only occurred with the custom tunes, I replaced the spark plugs and the COP's (Motorcraft PZT14F plugs and Motorcraft COP's) thinking that I had a bad one, but it did not fix it.
I would appreciate it if you could take a look at my tunes and see what you can do. It has become quite a problem recently as it is sputtering more often now. It used to do it about once a month or so, which I could live with, but now it does it about 1-2 times a week. It's got to the point where I'm thinking of abandoning my custom tunes and reloading the canned tunes on my Gryphon... PLEASE HELP
