Reduced Engine Power Part 2 plus Service 4WD.....

[BADRAP]

Well I tried to uninstall the Granatelli Diablo porgrammer from the H2 and once again I get the REDUCED ENGINE POWER on the display and this time I got SERVICE 4WD, and it would not do anything. I had to turn off motor, reinstall the programming again to get it to run right, then I had to go thru the DTC codes and wipe those out, then make sure everything functioned properly... What is up with that? I saved all the stock info so that in case something like this happened I could just uninstall and now it seems as if I can not take out the programmer for fear that the H2 will not run right and then the dealer will not take it back... What to do???
