IanL - thank you!
I had to go and get my re-test done yesterday before I could replace the EGR Solenoid (I only had 14 days to get re-test done for free), so I set the timing down to 3*, and put on 27" tires. They also ran the test within 10-15 min of me being parked, so I suspect the CAT was warmer than last time (sat for 2 hours).
I still failed because I threw a code P1530: Ignition timing adjustment switch circuit fault. I suspect I threw this code when I put the jumper on (bypassing computer) while adjusting the timing can anyone confirm this? I'm also concerned because I barely passed the HC side of the test, and might fail a re-test:
15 MPH max 63, and measured 63
25 MPH max 47, and measured 34
What else can be causing me to have such high HC?
