Hi all. I have been messing around with my ms for about 2 months now. I really like the layout of it but the performance is killing me. My idle is very unstable. I have checked all the usual things. Plugs, wires, coil pack, injectors and compression. I even had the stock ecu running the injectors with no problem. It sounds like a miss with the ms running the injectors. When driving the car it runs great. Why would my idle be unstable. It seems to be unstable under low map too. Like if I put it in neutral and coast the car misses and the afr goes from 13-20 back and forth. Here is a data log of my idle and If I can I will post my msq file. I am running msns-e, with the v3 main board. Also my stock ecu is running spark still. Thanks all.
Sam

I got it today. The injectors I bought were crap. I installed a set of used bluie tops from a turbo dsm and it idled great. Wow I knew I wasent crazy.
