So I am in a confused state. I have had a few P Codes and  I changed 02 Sensors and changed the Cats. I still have slight miss or a small ide issue. I thought that I would have Injector issues but I ohm them out and  I got the following reading I got 14.5 ohms on all injectors,; I am not convinced I have bad injectors. I have good voltage to O2's, The only thing that I have not done is smoke test. Could I have a bad fuel pump or could it be something else? Any ideas or where to look next ?

It would be helpful to know which P codes you had/have. It would, also, be helpful if you could describe the issue that you are having in more detail.

I still have slight miss or a small ide issue

is not much to go on.  Why do you think that you have an injector problem?

I have good voltage to O2's

What do you consider to be "good"? Are the upsteam sensors switching? What are the values of the downstream sensors? What do your fuel trims look like?


The more information that you can provide, the better the help that you will receive.

You can also see why I was thinking that would be a injector issue. I also checked coils and wires they are good

Actually, I can't. All of the codes that you have listed suggest an O2 heater issue.
