CAR RAN PERFECTLY, THEN I TURNED OFF, THEN I RESTARTED 5 SECONDS LATER TO REPOSITION IN GARAGE. ENGINE THEN REVVING FROM 800 TO 1200 RPM RHYTHMICALLY, APPROX ONCE PER SECOND, EML LIGHT ON, BRAKE LIGHT ON, SERVICE ENGINE LIGHT ON, VERY HARD TO STOP CAR, HAD ANYONE BEEN CLOSE I WOULD HAVE HIT THEM. ENGINE REVVING CONTINUED FOR 2 DAYS, THEN WENT AWAY ON OWN. I THEN TOOK OFF AIRBOX TO INSPECT MAF, FILTER. CODES ON 3RD DAY: P1632 THROTTLE, PENDING: P0102, IATS. THERE HAVE BEEN OTHER INCIDENTS OVER THE YEARS OF RESTARTING ENGINE TO HAVE EXTREMELY ROUGH IDLE, ALSO CLEARED ON ITS OWN, BUT NEVER SURGING LIKE THIS. *TR
