05 gsr drivebility problems. stalling.
Haven't had the car long, but I like it. Minus the fact it stalls.
Has full exhaust, 280 cams, 255 fuel pump, aem intake, greddy bov back into intake, test pipe, manual boost controller.
Sometimes when I push in the clutch to come to a stop the car idles down and shakes and dies. Watching the boost gauge vacuum sits at 6-9 in. At idle. Then when the car dies its drops low 0-2 in. Of vacuum.
When I turn on the heat or a/c, it doesnt idle up. Turn the wheel it should idle up, but doesn't. Other times it runs great and idles fine.
Got it tuned and tuner said Injectors are almost maxed out. Previous owner stated has a fuel pump. I'm not 100 percent. It whines and is loud.
No codes, but a p0300 last time it set a fault, freeze frame said -100 for short and long term fuel trim. Maybe something is causing a lean misfire? Car starts fine though. Wondering if anyone had some input?
Also, if it was the cams. Wouldn't it happen all the time. Do people with 280s have similar issues.

I just got it back from being tuned. Synaptic3 engineering did it, I'm pretty sure this site has a banner for them. They said the code couldn't be tuned out. I asked them about it. Maybe the tune will chime in.
I had mine disabled.
