Post by Jasonr23 »

Hey guys
One of your friends from over AUS. Would like a bit of assistance analysing my captures so far. Its an Aussie Ford Falcon XH 1999 model. Got the 4.0L 6 cyl. motor in it. seems to splutter during driving condition but is able to return to normal driving after a snap of the throttle. Only had time to get 2 wave forms.

1st is of relative compression test; high amp clamp battery pos (+), secondary pickup on no. 1 plug lead firing order 1,5,3,6,2,4. Cylinder 2 waveform a little inconsistent to others but not concerned with that.

2nd is of Fuel pressure regulator vacuum pulsation during idling;
