I have a 96 5.7 with 278000 miles. I had lower intake leak and just replaced the gaskets. After changing gaskets and putting back together i am getting very rough idle on startup. Giving gas bogs engine before catching up. Checked codes but none present. Live data shows missfire on 2 & 7. Both are close to 30 in 5 min run time. Others has under 5 each. I did put new distributor in and have checked plugs. Wires only have about 400 miles on them. Checked EGR and it is ok. Checked for vacuum leaks and didn't find any. Replaced MAF but didn't help. Stumped and not sure if it is the injectors or something else. Fuel pressure at 60 so that is good.
Any suggestions.
Thanks in advanced
