Motor is smoking in my '02 diamante, is it the gasket?

Smoke diagnostic is made by colour.
If u mean pistons head gasket,yes,it can smoke.
White (clear) water vapor.Ceck coolant level.Ceck engine oil colour by dipstick.

Black:runs rech on fuel (fuel filter/fuel lines/fuel mixture...)
Blue (whity):worn pistons rings.

Whity smoke before warming may be natural on cilli mornings with lot of compressure the engines just blows vapors.
Old oil/fuel residues in the exhaust tubing may blow smoke after heating the engine ,must track problem (...).
Black smoke on hitting the acceleration to the floor may be natural (overcharged) avoid sport driving style.

On my 2001 Diamante, when I start it, I have to push the gas pedle to the floor and hold it there b4 the car will start. Could this be a gas filter or mass air flow sensor problem?


Firstly, try to avoid depressing the gas pedal if possible, as this will flood the injection system.

Due to the intricacy of your Diamante's Emission system, this condition could be caused by any number of air/fuel components.

For this reason, DO NOT replace any parts, until you have had your diagnostic codes checked.

If you're technically inclined, you can check the diagnostics yourself by jumping the No.1 & No. 4 pins on your diagnostic connector (under dash, above driver's knee). Turn key to ON (do not star) and observe the flash sequence on your Check Engine light.

I have a mitsubishi diamante 01 ls im having trouble with the service engine light not wanting to go off the code is for the oxygen sensor bank 2 sensor 1 I have had two different sensors put in but none...

Hello, welcome to FixYa...your descripton indicates it's a heated 02 sensor that is setting the code...why would you not replace the correct one the first time if in fact it really does need to be repalced? ---80% of the time an 02 sensor code is set there is nothing wrong with the sensor itself, the sensor is doing it's job, it has detected a malfunction and reported it to the ECM, the ECM turned the service light on, that is what sensors do, that is how they work. I have seen motorist spend over $700 dollars on sensors and still have the same problem. On average the life of an 02 sensors is 60-80k. A good technician will know if a sensor is bad from the voltage it's drawing. You could have a dirty fuel injector or MAF sensor resulting in a rich or lean fuel mixture that caused the 02 code to be set. I hope you understand by this explanation, that even by replacing the $380 sensor there is no gurantee the problem has be repaired. A good diagnostic scan and someone that knows how to read the feedback from that scan could give you a clear cut decisive repair procedure.
I hope this helps and best of luck with the Diamante...
