I recently purchased a Gorgeous 97 etc, 3 days ago. Runs terigfic no codes. Drove around town all week no issues. Took 100 mile road trip in car tonight performed perfectly the entire way. Stopped at red light and 2nd gear start. Continued until ignition cycle ever since then fine. Read could be wheel speed sensor. Where should I start? 178000 miles, time set heads, junkyard Trans.
