Is this normal?
Is this normal? I plugged in a scanner I got from autozone to just mess around with and noticed that my spark advancement on idle is -20 and when doing a WOT it would range anywhere from -30 to -45. Now my car is completely stock with the exception of a Moroso CAI, but this looks really bad to me.
Is this normal for a stock car or is something up? What would cause it to be running so retarted, and what can I do to fix this.

Oh okay phew, we also checked it on my friend's Cobalt SS/SC and it was reading positive 10-17 on idle on his.
I guess my thought on it was that negatives would be the timing being retarted and positive would be advancement of degrees.
