There are two types of events where it seems to me the fuel management is acting wacky on my '20 Hemi. Wondering if either are "normal".
I should mention that in both of these situations I am in Gear Limiting format, so MDS is turned off (or should be). But in point 1 it DOES sorta sound like it does when going from MDS activated to in-active.
- When going to idle at highways speed. For instance, cruise is set at 55 and you start "coasting" because of a downgrade. I can hear a "burp" from the exhaust, and feel a slight surge in power, as if the throttle was blipped microscopically. It happens with or without cruise, I just mentioned that it does happen with cruise to show that it's not operator induced.
- Using engine braking at 2-3000 RPM. All of a sudden it lets go and is not holding back as much as it was, as if the throttle was suddenly opened a bit. IOW I all of a sudden need to use the brakes to maintain speed where it had been doing fine just on the engine before, on the same grade.
