THINK MAYBE --WITH A LITTLE TIME, IT MIGHT "RELEARN IDLE"THE UP AND DOWN MAY BE JUST FROM DISCONNECTING THE BATTERY, AND THE COMPUTER LOSING THE LEARNED IDLE.

IF YOU SORTA SEARCH AROUND ON OUR SITE, EVEN "YOU TUBE" COULD SHED MORE LIGHT ON MY SUGGESTION CONCERNING "RELEARN".I HAVE SEEN PROCEDURES IN WHICH MIGHT MAKE IT LEARN FASTER. THIS MAY BE SPECIFIC TO SPECIFIC CARS

IT COULD BE SOMETHING ELSE TOO, I'M MORE IN TUNE WITH OLDER NON-COMPUTERIZED CARS

MAYBE IT'S GONNA BE EZ AND NO HARM DONE
