I have been having a problem ever since I changed the intake gaskets on my wifes 1997 Jimmy for a water leak. On initial start up it will run very rough and almost die for about 2 min then smooth's out and runs good.


During the intake removal I broke the Map sensor so I replaced it. I also replaced the fuel pressure regulator.


I have checked for vacuum leaks but have not been able to find anything.


Fuel pressure is good I even replace the fuel pump due to the leak down test failing but that didn't help either.


I am leaning towards clogged injectors.


Below is the live data taking from my snap on MT2500. I also got the codes and freeze frame data. Any suggestions would be great.
