05 5.7 hemi slugish - underpower?!?!?
Ok guys, im getting worried. i have an 2005 5.7 hemi and im getting an error codes p0456 - p0152 - and sometimes p0420 but the p0420 isnt showing as of lately.
the real and noticeable problem is trucks is slugish but usually until 50 ish speeds. seems like as i try to give it alittle gas it just doesnt want to pick up speed.
now if i make it shift it goes but just bogs back down if i lift from making it shift. hope its not the cat,how can i tell and is there a way to test it out at home? not sure about these codes i posted?? it has 92,600 miles and i never towed with it, only coal during winter... any help guys would be great..
hope im not hurting it, this has been on going for awhile just worse now..
