Very likely
It's probably a head gasket problem.
I wouldn't even use it once, get the problem fixed.
I am have the same problem with my 06 Monte Carlo LT. Took to the dealer. Its a head gasket leak.
The 1995 Monte Carlo could have a vacuum leak. An engine vacuum leak can make the car idle up and accelerate.
Check to see if there is coolant on the engine block. It is common for the Monte Carlos, along with other GM cars equipped with the 3400 V6 engine to experience leaking intake manifold gaskets. A leaking intake manifold will cause oil to leak into the coolant system and even worse, for coolant to leak into the oil system.
I just had my intake gasket changed on my 99 Monte Carlo for the same thing. My cousin is a mechanic and has changed the same gasket on several cars with the 3.1 engine. The gasket is about $60 - $75 plus labor.
Yes, the water pump can leak if you do a coolant flush.
depends where the leak is comming from. If its the flex tube about $125,if its not really bad it can be welded.
White smoke usually indicates a water leak into the engine block. Blue or black smoke would indicate an oil leak. possibly pistons!! my 88 Monte Carlo did that
Evaporative Emission Control System Leak Detected (small leak) It is a very small leak in your EVAP control system. In fact it could be as small as 0.04' in in diameter.
Replace o ring between tank and pump clips slide off tank
They usually start to leak coolant.
