Nissan Primera III - Engine misfire? 2litre Petrol - gregc

Lack of power/misfire? at lower revs, tickover to 2000rpm, can be intermittent in severity. Engine cuts out at traffic lights if on tickover for thirty seconds but will restart immediately. Car regularly serviced, garage seems at a loss to suggest cause, nothing showing up on fault code readout. I have checked all engine compartment electrical connectors. Any suggestions on a cause or advice on where to look next?

Help would be much appreciated

This could be a MAF ( Mass Airflow ) sensor not responding properly. Disconnect it and see if it runs better. I have replaced several that were not reporting an error code. Regards Peter

Thanks Peter

I unplugged the thing and the symptoms were as before but more extreme. I think at this point I will gamble on replacing the MAF which is available for about £40 and take it from there. I will report back with the result.

Thanks again

What a wonderful difference that new MAF made, the car is powerful again throughout its rev range and does not cut out on tickover.

So many thanks for the tip Peter. I do after the changeover have "An emission control system malfunction" lamp lit on the dash, anyone know if this is resetable?

Given the choice of a car running really badly with no malfunction light on or a car rejuvinated but with a warning light, I definitely choose the latter!
