I just bought an 2000 Frontier. When I bought it the seller sprayed starter fluid in the mass air flow in order to start it. I was thinking I could just replace the sensor and that would solve my problems. After having it for a bit. It seems that the idle it too high. I have tried to adjust it, but can't. Someone thought that maybe there was air getting in at the intake manifold, but that doesn't seem to be the issue either. Any suggestions?
