Finally got the P0141 code. Cleared and came back a week later. I had anticipated this
happening since I have 115 k on the car. I was going to preemptively replace the entire
SAI system so In May I placed my order to Pelican and was going to install but with
temps at 100 deg i put it off. The Check engine light came and let me know it was time.
The cause of the failure was the vacuum canister had a small crack on the bottom.
Picture of the parts replaced.
