The car has a problem with the start. Sometimes it fires up at once and on the other time it has trouble and it seems that the engine is not sparking in the right moment because the engine seems to get stuck.
No trouble codes in the ecu. So i made a capture of cam and crank to see if the signals where good.
I did not have a known good but thought to check the timing. The timing marks on the pulleys where spot on, but my feeling sad something is wrong, so checked the tdc with the spark plug out and found the cam was one tooth of, strange because it did not set a fault code. Corrected the timing and made another capture, engine seemed to fire up at once but after a few times starting it struggled again. So I wanted to be sure to get a know good one.
Attach a view of the before and after capture, of cam and crank. The good one seems to be the same as the one Robski posted.
