There haven't been too many recent posts on 98 ES problems. I noticed yours on the high-mounted stoplight and I wanted to see if you have experienced problems with hestitation and jerkiness at 40-45 mph while at cruise speed (not acelerating or decelerating). This started on mine at about 210,000 miles. I have 217,000 on it now. My mechanic said he can't find the reason. There were no codes and no lights. Any thoughts?
