Check Engine Lite..Again!

Thanks guys! I'm feelin kinda lazy so I'm headed for my nearest Autozone!
Maybe keeping a suppy of EGR valves in the glove box will help (if I put 'em in).

heh its the pcv valve you keep in the glove box.. EGR valve is about the size of a soda can and cost $100-200 per lol.. the pcv valve is about the size of your thumb bent at the middle and cost $3-4 each

Well I went to Autozone like suggested. They plugged in a error code reader and got the code that the EGR valve was at fault. So I handed over $150 and headed home with the Check Engine lite still on. I stopped at a store and when I got back in and turned on the car a big cloud of smoke (like oil smoke= gray/white) blew out the tailpipe !!! And guess what!? The lite went off? Why would that have cured the problem?? Thanks guys!
