[Gmecm] 7747 stumbling acceleration when cold

[Aaron]

The timing light does all the work.
Like any other strobe light, it flashes and shows the fluid in the spray.
That flash helps your eye and brain pick out the spray.
I've always done it on the vehicle with the engine running.
That way the spark plug wire or coil can trigger the light.

It doesn't need to be a dial back timing light.
I just wrote what I normally use, but it's fun to spin the knob.

Out of curiosity, I'd like to check mine,. What's the best way to do this?
Just pull the injectors out. Is the vehicle running etc ?

Thanks
