I have a 2001 Toyota tundra v8 4.7
I ran the codes and it's giving me a p0300 306 307 and 305 codes I have changed the plugs but not the coils as of yet...so my question is if I change the coils and it still isn't running right could it be the fuel injectors? Also I did a compression check on the cylinders and all came out good.
could it be the fuel injectors?
it could be a lot of things.
misfire troubleshooting is in our FAQ on the main page.
I recommend running tests rather than throwing parts at it , or you're going to end up frustrated and poor.
