Ask for and share advice on using the PicoScope kit to fix vehicles here.
Hope you can advice me with the following.
Astra (G) from 2003 8 valve (Z16SE) with a double ignition coil.
Complaint: During acceleration the engine is loosing power. DTC P0300 and P0304 is coming up.
When i change the spark plug lead from 1 to 4 >> DTC P0301 is coming up.
I have attachted a screenshot from the signal to the ignition coil.
The question for me is - is it the ignition coil of the engine ecu?
Many thanks already

Hi Karel, so your codes are telling you not only a misfire on cyl4 P0304 but a random/multiple cylinder misfire P0300 if your code P0304 is changing to P0301 when you swap the lead then that lead is no good. That will possibly not address the P0300 though and chances are if you have one crook lead the others may be playing up too. Since you know you have one bad lead i would be putting a new set on it and see what happens, may well be all it needs. If you still get that P0300 then your going to have to dig a bit further.
Hope that helps
