EGR Issues
So I had the cruise set at 60 for about 5 minutes and then the ses light came on, it was the code 32 for the egr. It had done this before but I cleared the codes and it was fine for 2 weeks. What would i look for now?? The temp switch or the egr valve stuck, etc???

Re: EGR Issues
I'd look at the temp switch since it happened at cruise. Either the EGR opened and the switch didn't close, or the EGR didn't open, or it did open and the ports are clogged. The switches are known weak spots, especially if it's original. Could also be a bad EGR valve or solenoid.
