my 03 quad 5.7 does this 2 not all the time just here and there the service guy told me its the nature of the hemi something to do with the 2 spark plugs per cylender lol what a joke yea i told him its probably got a loose mufler bearing to some ofthese service guys will say anything to get you to just drive away

 

my 04 quad hemi does thison the cold mornings. turn the truck on put it in reverse and it sorta hesitates when you give it gas

 

I have a 97 dodge ram, and when i go out to start it after not drivin in a few hours it hesitates to start pretty bad. it happens every time, but if i start it, shut it off, then try to start it again, it starts up rite away. it even starts fine if i turn the key to where it trys to start, then let go, then turn it again, it fires rite up. and sometimes when i start it, before i shift into drive, it idles rough. does anyone know what i could do to fix this?

 

I had the same issue with my '04 5.7 Hemi, but would do it more below 50F.

I replaced the EGR valve ($40 O'Rielly's) You have to do a computer reboot or will continue acting up.

1. Remove #23 fuse
2. Turn key to on (Not Start)
3. Wait for lights to go out
4. Turn key to Start and hold until 2 beeps. (about 10sec)
5. Reinstall fuse and start, 1st time it wont respond, 2nd time will start.

Hope this fixes your issue.
