The buzz test is in numerical order 1-8.

That function (disable an individual injector) works in ForScan. I haven't used it for that, but @Hydro has.

 

Thanks for the quick reply, to make sure I understand, NOT by firing order but by cylinder order? Cylinders #3 & #6 (driver side).

thanks again

 

Not by firing order

 

Many thanks.

Can stiction cause a failed buzz test?

 

Yes .

 

I appreciate it, I caught it a bit after I did it. Trying to work & do this at the same time. I should focus on one thing at a time.

Those 2 failed buzz test on cold engine, passed on warm engine. I had a a bad cold & warm miss that was throwing codes, the codes stopped nearly immediately after oil change & adding Hot Shot Secret stiction eliminator. Only about 30 miles since the change but appears to be getting better rapidly. Will check again on cold engine by tomorrow morning.

I was planning to do injectors in the future when it gets studs, etc. Trying to buy some time if I can. Have a large trip planned, hope it doesn't bite me in the butt.

 

Also, I was trying to do an injector disable test yesterday, found it in the forscan (Windows) but could not execute the test to kill cylinders individually. Is that not an option?

Ayup, that function works fine

this on the 2006 in your sig line ? you didn't start out with that info

 

Yes, truck in the signature line, thanks.

 

Should be in the "vehicle tests" button (left side of the window)
select cylinder cut out and click the "Run" button at the bottom of the window
follow the instructions in the next window

 

I don't have that option in the tests, screenshots;

I found something similar in the dashboard section, under control but they don't appear to actually do anything when selected.

 

You are in the correct place -- add all the injector disable to the right hand pane and click OK to exit that window
on the main screen you will see a button to the right of the PCM that has an X in it -- click that - a control window will open where you can disable each injector one at a time
