so far so good one the first full day with the new IAC, i still feel like its running like crap, but then again while the fuel pump was out of mine i was driving a 2000 grand marquis, older person vehicle but damn that things smooth haha

 

update, everything seems good, did rev a smaller amount at idle, maybe 2-300 instead of 500-1000k, i recleaned the egr, idles a little too smooth im not used to it, also sometimes it will hesitate on acceleration if im sitting at a light

might take your advice and rent a fuel pressure test,
what are the specs again?
