Oledog63 Posted January 23, 2011 Share Posted January 23, 2011 I had a new rack and pinion and power steering pump installed on my 96 LS 400 with 179000 miles. When I got home there was a leak from the transmission speed sensor which the shop then fixed. Two days after I got it back the check engine light and the trac control light both came on at the same time and the car idles roughly. When first started and cold it runs smooth even though both lights are on but after warming it begins to run rough. Any thoughts? Quote Link to comment Share on other sites More sharing options...
