Diagnostic codes for a mitsubishi eclipse 2001 v6 p00100. mean

It is a MAS Airflow Sensor code. The sensor is either disconnected, damaged or the wiring to it is damaged. If you have installed custom/performance intake then that would be your issue, if not then you need to check the MAS Airflow sensor and wiring.

I have a 2001 mitsubishi mirage and my light is on the code are p0403 and p0421 and i want to know how to fix it.

Ok here is the way to get things done for free....are you ready???
Take the car to Auto Zone or Discount Auto and ask them to scan your comouter and give you a print out and a parts price and availbility of what the computer scanned codes are....they do this service for free, so if you buy the parts from them you will be able to bring the car home with all the needed litterature and parts to make a fair assumption that your vehicle will be fixed for a fair parts price.

P0403 - Exhaust Gas Recirculation Circuit Malfunction

CodePO403 does not go away

P0403 Exhaust gas recirculation circuit malfunction.
The EGR valve is not happy.
This may require a new EGR valve.
I would try fuel injector cleaner first.
Put a full bottle in 1/3 tank of gas a give it a good run....could be a piece of carbon holding the valve out of position.
Does it idle ok?
A rougher than normal or faster than normal idle speed could be a stuck valve.
