i was double checking the fuel system on my 98.5 to make sure i was actually needing a ip and lp. i have been having intermittant dead pedal at hiway speeds and the auto trans has been hunting 1-2 and 2-3 shifts around town. as part of the checks i disconnected my edge comp. after i scanned codes and got p0216 and p1693. a 50 mile test drive after clearing the codes showed more power and torque and the trans shifted normally. could the edge box have been causing the dead pedal and shift problems? i know the '216 code is a worn pump kind of thing and wont "fix" itself, and probly will come back later, but for now there are no new codes. can anyone comment on this?
