Motor Surging at idle

[mzunino]

Hey Guys
Just replaced alternator & starter on car. Now surging at idle. Guessing not tied to either but wanted to check where should I start to troubleshoot? Running the old FAST 2.01. Appreciate any help you can provide.
Thanks

Try raising your injector offset

It seems fine till it starts warming up then it starts surging. Does that change things at all?

It sounds lean

I adjusted the injector offset & that fixed it. Thanks Cal!
