For some reason when the temperature gauge is set to Cold and the gear shifter is anything but neutral the idle with drop rapidly until the its so low the engine stops. This started when is got warm and after I took it PFS for tuning and air fuel adjectment to remove backfiring. Backfiring stoped but this started.

I've got a remapped cpu , Apexi Air/Fuel Controller and
GReddy Boost Controller Profec Type S?

Anyone have any ideas?

Thanks

You have the answer in your facts.

 

Are we talking about a manual transmission that stalls the motor when you put it in gear, but keep the clutch pedal depressed?

 

Clutch switch.

 

Extreme_rotaty thats exactly what it does. Its been doing this since I brought it to PFS. The messed with the air fuel setting I believe to remove the backfiring. However this started happening. The wierd part is if I keep the stick in neutral it idles fine when cold but as soon as I move the stick to any gear and keep the clutch depressed, the rpms slowly drop to 0 in a matter of seconds.

 

Clutch switch.

Under 10 bucks and under 10 minutes to install.

 

I second that motion. Mine never stalled, but with the clutch depressed, it idled rough when I put it in gear. I fixed mine with the spring out of a ballpoint pen because the spring had broken. It's the switch at the top of the clutch pedal. Can't miss it.
