My attitude has been acting weird lately. Here's a partial list of problems:
1. MPH is reading about 1/2 of actual speed some of the time.
2. RPM and Load were totally inaccurate when the display was switched while driving (my son was making changes for me).
3. EGT's are now reading way too low some of the time.

Anyone else had similar problems or suggestions as to what may be wrong?
