I didn't want to be rude and not introduce myself when I registered yesterday,but you know how it is when you have mechanical questions in your head. Anyhow this is my or our first Cadillac,it's a 2000 SLS with the 4.6L,58,000 miles on the clock,runs really well for the most part(couple bugs)I joined like a lot of folks do to gain some knowledge,and as I learn I hope I can pass it on,thanks to the folks who set all this good stuff up. Peace for now,see you soon nccadikingz
