Hemi 5.7 bogs and dies

neverlift17 · Mar 28, 2012

its a 2005 ram hemi 5.7. when i slowly press the gas petal it will bog or die. if i blip the throttle it usually acts fine we just drove it today and everything was fine. its random as well.Any help would be greatly appreciated

I'd start with the easy stuff. Clean your throttle body and check your EGR valve.

Any codes?

Miles and are you up to date on maintance?

alright, no codes as of right now. i will check the gorunds i searched the forums and seen a similar problem and it was a ground. the truck was recently purchased last week from a car lot so who knows about the maintenance, however there are new pulg and wires in it.
i thought maybe a vacuum leak or egr but if its the ground hopefully i can find it. the thing i dont get is that 2-3 prior to it stalling it was running great

it starts and idles fine but once the gas pedal is lightly pressed it dips and rises and if i hold it there it jumps areound. If i floor it it will rev normal

The vacuum sounds like a good thing to check too. Never know.

thats what were doing now, the long term fuel trim will drop to -32.8 at time as well as the other fts bounce around between -3.2 and +3
