Greetings! I'm having part throttle issues with a 5.0 supercharged GT350. I was hoping somebody can shed some light on the problem. It has GT350 87mm TB and intake manifold. 550cc injectors. I included a log that shows the throttle shutting down under normal acceleration. Idle is fine, and fuel trims are good.
No such thing as a 5.0 GT350
ok so its a 5.0 with gt350 TB and intake?
Pro Charger?
look at your torque source when the throttle closes.
Right, 5.0 with GT350 TB and intake. It's actually low rpm, part-throttle, i'm fighting now. I've removed the air limit sources, and it still shuts the throttle.
that's odd Ive got a 2017 stick shift with gt350 intake & tb with almost identical problems ?
again, you dropped out of OP and you had a couple other flags when TB closed. Your missing shit I log. but your DD tables are used until 83.33 Pedal, Torque request is constant. I would first check out why you hit Trans Trunc. I think this is why your TB is closing and valves are going back into fuel economy.
