Check Engine Light, 51 Erorr

You could always just follow the pinpoint test.

Is that the emissions book @AndyB.

It would be in there. I pulled it from a different source.

Flash code 1-1?

Code 11 - System Pass

Means the ECM is operational

Just my ghost miss that nearly makes the engine stall, what a shame the computer can’t pick up on that….

 

[Uncle Gump]

Is it a dead miss or random?

 

[RumPunch]

Random generally under light to moderate acceleration. Just pulled original injectors back out cleaned and resealed all of them same thing. As it gets hot, seems to get better. Temp gauge still dead 0 but swapped original temp sensor and switch back in and error 51 code is gone. Still missing.

 

[Uncle Gump]

Random and not consistent doesn't make things any easier.

Did you use Motorcraft or Autolite plugs? Have taken a look at them since you changed injectors?

Haven't pulled plugs since bad injector incident fixed.. Motorcraft plugs.

Truck was hot for probably 20 minutes straight ran 90% fine hardly missed. Cooled down an hour runs like a piece of shit.
