During a long run round the Cotswolds my Sigma 4/4 began to drop power momentarily, cured by stabbing harder on the throttle. Mostly when cruising at a stable 2500 revs. Not when accelerating. This didn’t happen on a long run on Friday, so it’s a new issue. Just been serviced so presumably it’s been plugged in to look for fault codes. Seems a bit like fuel starvation but same fuel as Friday.
What would be a sensible fault finding sequence please? I don’t have a code reader but I expect Amazon could sort that for tomorrow.
All suggestions gratefully received
