Need Help with SES codes
 

Hi!

On my 2001 SL1 95,XXX miles I have the following systems codes and need help diagnosing them. The car runs well other tan a rough idle and I wonder if this isn't a motor mount issue?

Thanks in advance. I have the following codes 0133, 0301 and 0731. I have chnged the EGR valve and do not want to change anymore parts without a plan.

I need a plan!!!!

Again thanks
