because your ecu sends more fuel to warm up the engine faster
about 20psi at idle (warm) and 40 to 50psi at 2000rpm.

White smoke when cold - normal condensation burning off Blue smoke when engine is at normal operating temperature - could be bad valve guides or seals.
Plane engines may produce smoke during startup due to the combustion of oil or fuel that has accumulated in the engine or exhaust system. This can happen if the engine has not been run for a while, allowing oil to seep into the combustion chamber. Additionally, during the initial stages of engine startup, the fuel mixture can be rich, leading to incomplete combustion and visible smoke. Typically, this smoke dissipates quickly as the engine reaches normal operating conditions.
The Montero has an automatic Idle Speed control. The idle is automatically set during operation by the vehicles engine control module. If the vehicle stays at the 2000 RPM idle, check vacuum lines for leaks, replace the fuel and air filter, and check the timing. All of these can cause the ecm to improperly compensate. However, it is normal for the Montero to 'high-idle' often, especially when using the air conditioner.
Only on cold startup (diesel engine) it can be normal to get little black smoke, as long as it doesn't continue. If it continues after warm up that could indicate engine wear. I'd recommend a mechanical inspection. The newer common rail diesels though are generally cleaner burning than older engines.
Of course it is not normal. You have no fuel pressure at startup, and the engine is starving for fuel. Look at the fuel pressure regulator or for leaking fuel injectors that are bleeding off at shut down. This is definitely not normal and anyone who tells you it is, should not be trusted to repair this vehicle.
any make after 1997 will be susceptible to electrical issues when engine is normal. i wish they would have left the computer stuff out of vehicles. gauge is most likely electrically impaired.
The Caddy Seville? That is definitely not normal for that car to make a noise like that, maybe you should bring it in for inspection.
window start as normally
Depends on how well you take care of it I have seen them go up to over 300000 miles. But to put an average to it on a normal(non-M car) BMW engine 200000. with no major engine issues.
In a normal engine, no. In a high performance engine, maybe.In a normal engine, no. In a high performance engine, maybe.
