96 auto 4.0 with 242 390K on the odo.
Recently the speedo has gone wacky - after about 35 mph it starts bouncing anywhere from 40 to 125.
Also has started sometimes "bucking" when accelerating usually somewhere around 50 mph. does not go away unless I let off the gas and reapply.
Also CC no work - I am guessing because of speedo problem.
Also getting a 138 code for O2 heater. I do not have a rear O2 sensor connected - my cheapo generic replacement cat did not have a bung.
I changed the O2 front sensor a few weeks ago - but the speedo issue started before that.
Wondering if some of these problems sound related? or just coincidental that they seemed to start at the same time.
