I just finished cleaning the IMRCs, installing a 255 lph fuel pump, and replacing a coolant cross over pipe with a Vortech version. After I filled the radiator fluid, I started the car and it had a very rough idle. After 2 minutes, it had a little smoother idle. I topped off the radiator fluid and let the car cool down. After 3 hours of cooling down, I topped off the radiator fluid and turn the car on. It still has a rough idle and then the check engine light turned. on Do you think this is a vacuum leak, did I forget to connect something, or EGR issue. The car ran perfect before I decided to mess with it in anticipation of adding a Vortech blower. Any suggestions on what to check or do? Thanks!
