my 2001 dodge ram runs fine for a few days then without warning runs like crap spits sputters backfires....sets o2 sensor code and misfire in all cylinders....after about 15 minutes clears up and runs fine for a few days....I have found that during these times I have fuel pressure but mainly air comes out of the port......what could be the issue?
2001 problem staying running

If you are getting air out of the test port then there is air getting in the line some how. I have heard that a MAP sensor can cause this issue but I'm leaning more to fuel system since you mention air in the line.
