The oil pressure is high the motor shakes alot when stopped and the windshield steams up every time I turn on the heat any suggestions how to fix it without spending big bucks at a garage?

What do you consider high for the oil pressure? What is idle speed when stopped? Do you smell coolant in the cab with the heat on? windshield steaming up when the heat is on could be a sign of a leaking heater core

sounds like the core. I think I'd check to see if your getting compression into your cooling system. If that's the case you could have a blown head gasket or cracked head. That could cause it to idle strange and a whole bunch of other things.

Get that heater fixed ASAP! Ethylene Glycol (coolant) is toxic and will eventually kill you.

Well, PMing won't help unless you tell us the code. Do you mean a high voltage signal from a sensor? Tell us the code and we'll figure it out.
