Over the last week I have noticed that when driving between 30-40mph or 1500-2000 rpm, the engine constantly splutters. It makes no difference whether the engine is hot or cold and doesn't happen if you apply more pressure on the throttle. I got someone to run a check on it it and it came back with error code 34 - knock sensor. I had it service and the ECU reset and it was OK for a couple of days but is now back. Any ideas?
