everything was fine when I last drove my 05 G35, then it sat for probably a month or so due to weather and getting another vehicle...
about a week ago went to start it and it needed to be jumped started, drove it around a little bit then put it on the charger, later in the afternoon it started fine drove it a little bit and parked it again. just went to drive it and it needed to be jumped again... except this time when I jumpstarted it - it went straight to revving form about 2500-5000rpms... no idle... I do have an OBDII reader connected to the car and it didn't show any codes... I turned off the car and tried to restart it, had to jump it again and straight to revving again....
I searched and found only 1 related thread - difference was he disconnect battery, didn't need a jump start and his vehicle would idle for a little bit before revving 1000-2500rpms...
