Come to think of it, why didn't you s**tcan the original injectors in the first place? One of them was the root cause of all of this!

 

Most likely cost was a factor. I remember when the extended coverage was active the warranty cost for the injectors was $9 each. Ford plays some dirty tricks with their parts pricing.

 

 

#5 is closest to the radiator. You said it runs good but has a rough idle? Ignition misfires usually are the opposite, it idles fine but runs rough at speed. You could try moving the injector on #5 to #6 and the coil on #5 to #7 and see which cylinder sets the code. Too bad you don't have a scan tool with power balance capability.

 

 

$5 says it's a bad injector.

 

I don't know WHICH one that would be. There are several that 'purport' that capability. But my exhaustive efforts shows that the task (power balance) requires communication rates that surpasses any Bluetooth adapter/ scanner that I'm familiar with. With direct USB connection set at 500k you might get a clean reading if the OBDII scanner equipment was fast enough. I have the PID # that displays the cylinder number that each ignition pulse is sent to. The number changes so fast that Torque Pro (with Bluetooth adapter) can't even keep up logging ONLY that single PID. It should show the firing order - repeating over and over, but it just skips all over the place. FWIW.

 

 

No, just 'spaced-out' most of the time trying to figure something out!

 

He is like a nasa engineer .FT --deep space God he can my my head hurt following his in depth stuff but in a good way .

 

 

Pull the spark plug and do a compression check, then check the compression on #1 cylinder and see if there is a big difference. You could just have a bad spark plug.

 

 

Did you make sure to clear the codes after swapping around the coil and injector?

 

@70f , yes I erased the codes. I can tell something is missing by the way it's running. It's not horrible I have acceleration but it sounds like ........? A boat exhaust.. Its miss firing for sure
