2001 Buick Lesabre 6 cyl Front Wheel Drive Automatic 75000 miles
The service engine soon light was on. Code reader gave a P1404 code. I changed the EGR valve and cleared code. After driving for about 15 minutes I stopped the vehicle then restarted. Service light was back on. Car runs very good, no apparent performance problems. What is my next step?
Thanks, Earnest T
