Another idle issue
I've searched and didn't find much, although I think my solution may be in the ignition timing trims thread, I just need to read a little deeper.
Anyways. During warmup my car idles like crap, afr/timing bounces all over, usually throws a p0300 (unless I tap the throttle to keep it from going full lean on my WB) and is pretty much undriveable. But, as soon as it hits 154.4* according to coolant temp scaled, it jumps from 1000ish rpm to 1500 rmp for a second, and drops back down to 1000ish, but now idles absolutely perfect with stable afr and timing.
The car has an APexi filter with stock intake, M2 cams, and PTE 1000cc injectors, v5.10 rom with FAA bits 9 & 10 disabled. I'd like to figure this out on my own, but need a little help getting pointed in the right direction.
