Hi, my Rover 75 lost power and had power fluctuations on the dual carriageway, and so I pulled off and called the AA. The fella duly came and diagnosed it to be the MAF sensor, unplugged it and I returned home without fault. Before replacing it I thought I’d just try cleaning it. So I’ve done that with contact cleaning fluid, put all back together, but the engine light is still on. Does it mean the MAF is still playing up, or will it need to be reset. Haven’t taken it out for a run yet. Any advice welcome. Thanks!
