P0302 2002 Ford excursion

Question

Got P0302 AND 316

Changed the plug and ignition coil. Ran great for 10 days and started acting up again and gave the same code 302 and 316. Removed the plug and it looks white on the tip like it is firing good. So I replaced the coil again but the same misfire is their this time with the same code.

Should I change the fuel injector in cylinder #2?

Answer 1

Hi there,

That would be the next step. What I would do is swap it with the one next to it and see if the misfire moves with the injector. Then you know it is in fact a bad injector prior to buying a replacement.
