seat ibiza 2010 1.2 stall missfire

Postby picocj » Mon Mar 06, 2017 9:37 pm

Hi i have a fault with a 2010 seat ibiza 1.2 petrol 62000 miles. Concern is mil lamp on misfire under load, stalls when backing off throttle sharply. code p0341 16725 camshaft sensor signal implausible and also had a p0106 for manifold pressure range/performance but this code had not came back since clearing. Vehicle runs okay at idle carried out cylinder balance check and all looks well. checked signals at both the crank and cam sensor please see attached ps data file. I suspect the timing is out, can anyone help me with a known good waveform and if you think the timing is out? I have had a visual inspection and does not look too far away but i don't have the timing tools. Any suggestion or help would be greatly appreciated.

Regards, picocj

Is this the Chocolate 3 Cylinder Engine that suffers Chain Stretch and Jumping ?

Concern is mil lamp on misfire under load


Could you get a capture whilst it is under load with the fault occurring ?
stalls when backing off throttle sharply.

Again a capture, of it stalling - What goes missing - Fuel, Spark ... ... ... ?
