MS2 Standalone on '99. 2 minor issues/ questions
 

My megasquirt has been running my car very well for months. I guess I'm getting picky, but I have 2 issues that drive me nuts.
1) My car idles between 1100 and 1400 RPM, and nothing I do seems to change this. If I plug in the stock ecu, it'll idle fine, so that proves to me that it's megasquirt related.
The idle didnt really bother me as that was my only issue, until I swapped in my 460 cc injectors.
2) Ever since I swapped in my Brand New set of RX7 PNP 460's, when I turn on the key prior to cranking, I will occassionally get that infamous "pop". I'm thinking it's a spark out problem, but does anyone have experience with this issue and know how to correct it?
I love my MS and don't want to give up on it, but these 2 small issues are really getting under my skin.
Thanks

I'm at work right now, so I can post requested screen shots when I get home. Thanks ahead of time for help and input.
