hey guys i have a 01 f250 7.3 and i have a new set of injectors reman stock from full force. new ipr new icp sensors.. as soon as i put the injectors in the truck ran great for a few hundred miles then developed a shudder feel around 40 mph -45 mph. so i pulled them out and sent them back in. they said 3 injectors were off and not flowing with the rest so they fixed them and sent them back. the truck doesn't shudder anymore but i am getting a vibration in the pedal when accelerating at 1400-1600 rpm at around 40 or so mph. i notice it mostly when the truck is up to temp. i called full force and they said its something on the oil side of the injectors probably.. i just hate to pull them again. new oil and no change always changed the oil on time and everything..anything i could try or should i just send them in? also a couple questions when they flow text them does that check the fuel or oil side? also i have ae how could i check my hpop on it? i know look for icp psi and get around 60 and put the throttle down hard. what should i look for? thanks guys

 

anyone with any ideas?
