Please help,
My Focus 1.8TDi has developed a problem, the glow plug light on the dash starts to flash and the car loses all power. The engine continues to run, but there is no acceleration at all. Switch it off then on again and away you go. Its is becoming more and more frequent and is especially bad, the slower you go. I love the car, but can only just afford to keep it on the road and cant afford to spend money on scanners etc. An uncle has suggested over the phone, that it might be the Lambda sensor. Do diesels have them? Cant find it listed in parts websites. Does anyone have any ideas what it could be?
