Ocassional stall while idling 1998 gt3


Recommended Posts


GT3 1998 with v8 style dash.

Very rarely.. but fIive times over the past year.. while idling it just stops.. restarts everytime.

If I am coasting at the time (to save my left foot) I can bump it in gear and it starts before we have stopped rolling


Not really a problem... but it must be symptomatic of something not quite right... throttle sensor ??

Like Barry said, most likely an IAC issue (Idle Air Control stepper motor). It may just need a reset, or a cleaning.

If that doesn't help then there is a procedure in the EHM manual to adjust the minimum air rate bleed screw to the proper range so that IAC is between 20-40 counts (monitered with freescan or Espritmon. DO not adjust this screw by ear, as that will mess with the ability of the IAC to control the idle.
