Surge when warming up, worse after oil change

My truck for the past couple years gets a chug/surge going on as soon as the temp gauge gets off of cold until it warms all the way up. Gets worse with fresh oil. Any ideas? Injectors, hpop?

Also doesnt do it under accel/decel, just while cruising at any speed

Did you put any oil additive in there when you did the oil change?

you should try changing the oil in the HPOP. theres a fill screw on top of the resivour. use a brake bleeder or some sort of vacume to suck the oil out (it holds about a quart) then fill it and run it for a minute and it will fill with the nasty sludge oil again, do it like 3 or 4 times youd be surprised how much it helps

Didn't use any additive this time. Have used lucas before with no change. I will try the hpop oil, thanks
