I have a problem that has not been solved by the dealer but maybe the great minds on here could help. I have found a few articles on this topic but no real resolutions. I have what smells like rich, oily exhaust coming into my cab unless I have the recirculating on. Gets worse when I come to a stop or right at startup.
Been to the dealer but they were of little help. They replaced the tranny in April so I was sure it had something to do with that. I checked underneath but could not see any signs of an exhaust leak. Today, after coming off a road trip, I checked it over again and found this rattling around by the fuel rails. Can someone help ID this and where it belongs? I have a feeling there is a heated call in the near future. Thanks for any help that you can provide! Btw, it's a 2007 with the 5.4.
Update: I had a closer look and managed to find a finely engrave p/n OTC 310-122 which turns out to be a fuel pressure connector. Likely left there when they replaced a bad injector a YEAR ago. Damn, I thought I was onto something. Any help is still greatly appreciated though for the exhaust smell. I feel so bad when I have to pick up kids. I don't want to be poisoning them with CO.
