It keeps saying this in the info panel. At first is was coding lean, P0170, P0171, P0174 and we diagnosed this as the MAF sensor. After replacement, it immediately coded P0113, which appears to be the IAT sensor. So, was the IAT the problem all along and the MAF wasn't necessary? Or are these all little codes that mask a larger problem (like an intake manifold gasket or some other horror?) Don't be afraid to ask if you need more info, and thanks for any help!!
