Bad or weak injectors???? maybe

[oldbiker]

96 F350 372k, When I start the truck in Park the idle rpm will rack back and forth...is just fine if I start it in Neutral...or if I shift it to Neutral after I start it in Park... I was told that indicated week or a bad injector.. I can get injectors at cost from International as my dad sold heavy trucks for them and has connections:yay:...The parts guy wants me to pull one and give em the part number off of it... Now my issue... this truck is used only to drag my antique bass boat and a bed load of camping gear to the lake ( gotta climb 7,000') maybe 6 times a year (bout 450 miles round trip) and once a month or so I'll haul a heavy trailer load to the scrap yard.. The first 300k on this truck was spend running bull semen from Amarillo to Houston.. has a little warn spot on the back seat from the cooler...lol... anyway...it uses about a quart of oil every oil change.. has always Dello in her... With all that said...should I keep the same injectors in her or do ya think I should do something different Is stock engine...no chip, no exhaust work...nadda...just like Henry Ford wanted her to be...

any codes.. on this truck.. I would think its more of a sensor prob.. maybe even a prob with the hpop loosing oil over nite.. you really need to scan it an see whats going on.. sorry to many people just wanna change out inj.. (heard this from serval vendors) an if you were to change i would do at least a small upgrade to stage ones. will make pulling your boat up the hill a lot easier... plus fun..(ps you will need a intake an exhaust an gauges too)
