The intake gasket could cause the MAF code and a rough idle when cold. But not the coolant issue. The intake is a dry intake. It doesn't have coolant running thru it. Check the water pump for leaks

2005 KIA Rio belts have been making noise. Now check engine light is on and I get codes p0101, p0101 pending, and p0170 pending?


Basically the P0101 diagnostic trouble code (DTC) means that there is a problem with the Mass Air Flow (MAF) sensor or circuit.

P0170 means there is a malfunction in the computer's control of the air:fuel ratio.

    Those are lean codes and a MAF (P0101) code. Make sure the MAF sensor is plugged in, and there are no leaks/ loose hoses between the air filter and the engine. You may have a vac leak at the intake also, but check these first, If all appears OK a repair shop will need to check it out for you.

    Yes, replace the MAF, then check if the lean condition goes away. It should.

    MAF's are sensitive to cleaning. Sometimes it works, other times it doesn't.
