Running Lean with Idle Issues

So I have recently completed my e2i conversion on the 528 super eta, but when I start it up, it
i have to give it gas to get it to stay on. When the engine runs, it has a bit of a sporadic idle for
a minute or so, then goes smooth for a bit, then back to a sporadic idle. Along with this, I think
the car is running a bit lean as the exhaust smells a bit sweet. Any suggestions? Do you think I
would adjust the throttle line to open later when I give it gas so it doesn't get as much air thus
theoretically not making it run lean?
