My buddy asked me to post this for him. He's running a PR3 ECU with the Mugen program. When the car reaches normal temp it throws an intermittent code 86. It'll sputter at low throttle and then die out. He'll restart it and it'll be fine until it gets up to temp again, then it starts all over. Anyone else have this problem, and what is code 86? Thanks in advance.

circuit range / performance problem

Sounds like it may be the coolant temp sensor.
