Never heard of that one. You can change the speedo gear in the trans attached to your vehicle speed sensor. More teeth slow the speedo down. count the teeth on the one in there and see what the dealer has. about $5 each.
TEst for slipping clutch is travel about 30 mph. press clutch, shift to 3rd, rev engine pretty high and release clutch, at the time of clutch release, floor throttle. If the engine continues to race, clutch not grabbing porperly, if the clutch works properly, the engine will be slowed and engauged.
You can always get a 2nd opinon from another shop.
the 85,000 mile coutch worn out issue dependes entirely on driving habits of the operators.
means your egr is malfuctioning or needs to be cleaned. the high imput means the egr is allowing for exhast gases into the combustion chamber and the map code is caused by the egr as well.
