My 00' GS-R has been acting wierd lately. It started about 3 weeks ago, every few times i go to start it with any heat in the engine it happens. On startup the ECT registers -40 degrees and throws P0171 - too lean and a generic fuel trim code. It goes away within 2-3 seconds of startup. The ECT sensor is less than 6 months old and the wiring is good. About 2 weeks ago I checked resistance on it and found the wires were broken at the sensor connector so i soldered a new connector in place. Still the issue keeps happening. Anyone seen this and know a possible cause?
