rough acceleration
so heres the deal...its an 02 f250 w/ 5.4l v8...driving a week ago and the altanator dies...so i change the altinator...right after changing it,it has rough accelearation and abs light comes on while pushing accelerator and speedo bounces on highway...i changed the vss/abs sensor on the rear diff...this solved the abs light issue and speedo bounce but still low power while accelerating...i chaged the pcv cause well,,,it needed it,and changed the fuel filter but still same problem...the injectors are not stuck open and all the ignition coils read correctly at 0.6 ohm...no trouble codes either...idles at 750 but goes up and down 500 rpm depending on the moment...almost feels like a missfire while accelerating...any ideas?????????????

ya i had a look at it and it seems to be in fine condition,no breaks or crushed points in the harness...i even cleaned the clip connection before sliding it onto the new vss with elect. cleaner...ty for the welcome also...ive used this site for years as i work on 7 different ford trucks,4 f150's,a superduty diesel f350 dump dually, and a couple f250's...ive always found my fixes in the forum pretty quick but this one got me alittle loopy,lol
