Hey jbizzle,
I got the same problem on my stock cd player that came with my SiR. I tried cleaning it it did not work. I'm going to go get it repaired at Magneton on Décarie and see what's the problem.
If you want their number its 514.486.6454 I got recommended to go there. They guy's name is Mickey.
PM me if you want so we can see what works so we don't do it in double.
Cya
