The EGR port was serviced around 80K under a recall. I believe it was replaced by a new kit. I haven't gotten that rechecked but I can't imagine that going bad in 20k miles. I might get the fuel pump looked at. Is that something I can test on my own or are there any other signs of a bad fuel pump? In a way, im hoping that this problem becomes permanent so that I can reproduce it to the shop.
