AS I DROVE INTO OUR PARKING LOT AT WORK AFTER LUNCH, I WAS IDLING ENGINE WITH FOOT ON BRAKE AS I PULLED INTO A PARKING SPOT.

MY EDUCATION IS IN MECHANICAL ENGINEERING AND I HAVE BEEN AN EQUIPMENT MECHANIC ON MACHINERY FOR 15 YEARS. I DO NOT BELIEVE THAT JUST BECAUSE YOU CANNOT REPRODUCE AN ELECTRONIC PROBLEM IN A MATTER OF HOURS THAT THE CONCLUSION SHO
