Hi,
Had this one in as it is hesitating.
Fault code for lambda sensor and in live data it is showing lambda voltage dropping to 0 and staying there, so i fitted new o2 sensor and its still the same.
I have checked cat and exhaust for blockage.
Checked fuel pressure and hold pressure all ok.
Checked valve timing all ok.
I have scoped the coil pack and on idle the pattern will drop out every now and then is this correct?
I have uploaded pattern.
Any help please?
