low idle problem
Been having an issue with my FD with hot starts. When I start it up, it won't stay on without some assist from the gas pedal. Then driving around the next couple minutes when put into neutral it will drop the rpms to 500ish, before coming back up to 800.
Current modifications to car: PFC, full 3in exhaust, air pump delete, meth injection.
Also, before I get a lot of low compression answers, I recently had the car taken for a compression test as well as a tune at Rotary Performance, and everything checked out fine.

The tune was fine, but it doesn't idle well? Did it start having issues right after the tune or something? What are the readings of your injector duties? Without actual numbers, it's going to be hard to determine the problem. Maybe get your tuner to see what is the matter if it was done recently.

Just during idle? I think my injectors are at around 3-6%? I'll double check next time I drive it. It also happened before the tune, and was one of the reasons I got my compression check done. Leaky injectors possibly?

Alright so now a new problem has arisen. Now every time I start it up warm, it dies without throttle. Not just hot either. I can get it going, cruising at 70mph, water temps of 83-85, step on the clutch and the car just shuts off. The attached pictures are of the pfc, with me giving it the least amount of throttle possible to keep it alive.

Confirmed that it only dies when it's warm. Just cold started it this morning and started right up and stayed on. Although, normally it idles around 1100-1300 on cold start ups, now it is only sitting between 900-1000
