A friend of mine has a 04 Ford Expedition that after starting has a rough idle and sounds just horrible it barely would start and dies right after starting it if you don't give it some gas. It sounds like it's a few degrees out of time I did notice a few vacum leaks one from the pcv to the intake manifold and another to the erg sensor could these cause it to run this poorly it has new plugs I put them in not to long ago or ran fine after. I live 45 mins away do I haven't gotten over there to fix the vacuum leaks looking for any suggestions at what to look at besides the vacuum leaks before I get back over there to fox the vacuum leaks. Thx
