Hello all,
Looking for some help pinning down a problem that just started with no warning- start my 2003 4.0 xlt couple mornings ago and wait for idle to settle as usual, drop into drive and at about 1000 rpm and truck takes off as if I was on the gas and has a miss that wasn't there before, pretty strong miss at that. When I reach first stopping point it acts as though it's going to die and proceeds to jump, literally like it has a built v8. Had codes pulled and got 4 o2 codes , 2 from each bank. Not knowing much , I replaced both upstream o2 sensors and while driving can feel a small increase in response but idle still high and still just as "jumpy". Have not made it back out to have codes read again as I am without transportation. Anyone experienced this or have any ideas ??
