What injectors? What AFR are you tuning it to? How much timing are you running at idle?

LED Light Emmiting Diode the red flashing things on your ECU

the middle one is warmup enrichment IIRC.

what Braineack is getting at is if the idle goes to pot when the middle LED goes out your VE table/req fuel is wrong and the WUE is masking the problem.

The LEDs on an MSPNP are not visible - they're on the inside.

This can be either a further vacuum leak, or just a matter of a bit more tuning. Could you post a copy of a data log of it idling and your MSQ file here?

If you ZIP both your datalog and the MSQ into one folder you can upload them in a post on the forum.

You could just email it along with your current .msq file to our support guys at websales@diyautotune.com, that's probably the best route....
