decided to go ahead and try to clean the egr, ended up not being able to take off the second bolt which is located right below the metallic pipe, the one towards the front of the car. and when I was trying to figure out I started to receive Tornado warnings on my phone so had to leave it half done. it was 80 and sunny when I started to work on the car, it was below 50 and raining when I gave up. San Antonio classic :/
