05 1.7 misfire on no 2 cylinder - Pedro Frommetti
This petrol merc has a misfire on no 2 cylinder, compression is good, coil packs and plug leads all good. using the laptop all seems to function as it should but it counts the misfires and then puts the management light on. The local wizboys are stumped ,and now we have removed the head to check for problems to no avail . Do the ECUs go down and if so can it affect just 1 cylinder ?the people im asking say they cannot test this ECU

More than likely a faulty injector or could be a plug lead breaking down.
