K for those of you that may know my previous threads I have a rusty '89 SCab with the zf-5speed that chirps going down the road, well I have an old problem that is slowly getting worse, when I downshift to slow down like at 45 mph in OD shifting to 3rd which brings the RPM's to around 2900-3000 it surges and bucks about 3-6 times with NO throttle applied, it feels like it is getting MORE fuel when it bucks because it slows down less and the engine sounds different when it happens, it will only do it when the RPM's are above 2800ish. When it bucks it is enough to shake things in the truck a bit. BTW what is the governed speed on these engines, this thing revs to about 3500 before the limiter kicks in but I think the gauge/sender may be going out because it does not work very well cold and when cold when you turn the headlights on the gauge drops to 0 until you rev it.
