loping at start up

[97psd16.5mpg]

my truck is loping when i start it up. doesn't matter if i run 100 miles i can turn it off and start right back up and it will go to loping again. i can idle it up just a little and hold for a few seconds and it will stop. it's doesn't seem to be hurting anything just annoying and would like it to stop. any help/advice would be greatly appreciated. thanks

an ipr can cause this issue , ive seen a couple trucks with the trans range sensor causing that also , just touch the gas and it will go away , are you getting any codes at all or have you had it checked

The ICP can do this to..
