lots of heavy junk in trunk, under inflated tires, open windows at high speed instead of using AC, clogged gas filter, weak spark, excessive bearing friction, excessive speed on road, jack rabbit starts, slipping transmission, dragging brakes, etc.,

You replace it only.

Make sure no hoses came undone...and u can try a idle relearn procedure to start off with..may b coincedental that something may have went out of sack w hits

Is the water pump working or did you damage it during the freeze up.
Watch for coolant flow, if you have to splice in a clear piece of hose.
Head gasket?
Block damage?

first, try to clean your throtle body with a good cleaner an a tooth brush, open buter fly and clean all around, front an rear, when starting it hold your gas pedal down until it starts letgo quickly but keep it running at 2500rpm until engine clears(some smoke may be heavy) this will help with idle problems and clean some carbon from valves and combustion chamber,.second your egr valve may be gettin partially stuck open, disconect hose from top of it, use a small bolt to plug vacum hose and drive it normally if problem doesnot occurs you need a new egr valve,
good luck.

Overdrive is used when pulling heavy looads or traviling on highway at high speeds, good luck.

Did you clean the fuel injectors? these always happen when they are blocked.
