Well ours says 43 so i'm not going to argue the point it should go up. The dieseling can be form idling to fast, as far as the sputtering have you tried pulling one plug wire at a time and i'm assuming the dist cap isn't cracked or carbon tracked. If ou pll a plug wire leave it like 1/2" or so maybe less from the plug and see if it stops sputtering, if it does then the plugs aren't in good shape. Also if you pull a plug wire and nothing happens like rpm going lower then check compression on all cylinders this may be a blown head gasket which I've totally forgot about. Way to check that is to have coolant system pressure checked for an internal leak. If it doesn'thold pressure then it's probably that.
