Hi Scotty,

I recently changed the fuel injectors on my 2007 Saturn Vue 3.5l v6 awd. It has i believe 175k. 

I was getting random misfires and then misfire in cylinder 4 and a flashing engine light. i also replaced the coils and spark plugs. I also had to replace the gasket and studs on the exhaust pipe, which i finally put it on ramps to see if i had an exhaust leak and I did. We've had this car over 5 years now and its been great until i parked it to figure out my misfire. So it sat for awhile since i am an older female that lives on the East Coast, weather and work made it hard to get to, since i don't have a garage. This one thing has me baffled. Could it be the IAT? No, I only get the IAT code when its disconnected. Any suggestions are greatly appreciated.
