I have a 05 ram quad cab 4x4 140-160k miles was a motor swap back 4 months ago!! Well it is acting up n I'm hoping somebody may have the answer for me. So here is the problem it starts and idles fine can even take it up is fine fuel pressure is around 58ish when rev it drops 56ish n right back to 58. But when in gear driving it sputters and hicups but has bever back fired. If you manually down shift it will go and be ok. Shift back to drive its ok for a bit then it will hicup. Its seems that it does it at a steady speed or when its bogging and needs down shift. If anybody could help id be for ever thankful
