My 1997 Tahoe is overheating. I have replaced the radiator, water pump, thermostat, and fan, but it is still overheating. It is also smoking like crazy out of the tail pipe. I hooked it up to a OBD 2 scanner and it threw these codes out:

MAF/VAF A circuit low input P0102
Close loop fuel control insufficient coolant temp P0125
O2 sensor heater circuit malfunction Bank 2 sensor 1 P0155
Enging coolant circuit low input P0117

What do I need to do to get this thing running right?

What color is the smoke you're seeing?

It is a really thick white smoke.

That means you're burning coolant. You have either a bad intake manifold gasket or a more serious blown head gasket.

What am I looking at price wise to get that fixed? I don't have the tools and know how to do that myself.

Nobody knows unto the engine is taken apart and the degree of damage is determined.

Do you think $1000-1500 will take care of it?
