do you get "shift range inhibited" on the DIC and a reduction in power? Do you have a check engine light when it does this? When was the last time you changed your fuel filter? If it has been a long time (over 5000 miles) change your fuel filter first. As far as checking the codes, you can go to the local Autozone and they should be able to pull the codes for you. Also, I believe there is a TSB out for the #2 and #7 injector harness chafing. Also, what power level are you using on the Juice? There is also a tranny spin on filter that needs to be changed at intervals probably no more than 10,000 miles. This is about all the help you can get without codes.
