Question

98 nissan altima has codes po100, po301.it was starting up but has stoped .However it turns over like it wants to crank.

Answer 1

Hi there,

The code P0100 is for a faulty mass air flow sensor. This can create hard starting and loss of power once the car does actually start.

P0301 is a misfire on cylinder 1. This can be caused by bad plug wires or a problem with the intake manifold gasket.
