How long have you let it run? I had a bad tune (W4M) that would need to learn to idle. It took a a few seconds of me not touching the pedal and letting it try to run on its own for it to pick up. After learning it would be fine until you disconnected the battery, then I needed to let it learn again. Sent it back to him twice, same junk. Different tuner got it the first time.
