09 assault low end BOG?

[batteryoperator]

Hey all, Just wonering if any one else has had this problem and what I should try? Took the new sled for a ride today ( only has 24 mi now). And it seemed to hesitate or bog when going from slow rpm to high rpm fairly quickly. If I went easy on the throttle it was fine. Changed plugs and tried with the ehanol fuel wires both connected in and disconnected didn't seem to make much difference, not running ethanol fuel but I am running regular pump gas with STP Octane booster. Any ideas on what could be causing this bog when I try to hit the throttle hard?

Check to see if your dealer premixed the first tank of fuel for you. If so, that could be part of the reason. It'll run pig rich until the first tank is gone. After that, swap the plugs, keep the ethanol wires connected and hang on....I have 135 miles on mine now and it runs fine.

I think they have to run a certain distance or time and then the ignition goes to full advance. This could be a case of "It'll fix itself".

watch engine temp. anything below 118 and the pipe is cold and it will bog
