No, that is my real question.

Hi Im David, you need to find out which cylinders are misfiring so we can start checking the wiring to the ignition coil and the fuel injector, so I would suggest, unless you have a code reader, take it to auto zone and have them put their reader on it and write the code/s down to let me know what they are.

P0307 ob code. I think I saw the wires going to fuel injectors and
they looked find, So how do I test them to make sure they are OK?

I figured out that if I put a current probe around one of the wires to the injector
and look at the result with an oscilloscope , it would test the entire electrical path. But,
It has been snowing here and very cold and wet outside, so I will do that test when the weather improves.
