Hi Sajeev & Steve,
“You have not covered extensively the problems encountered by GDI engines, especially Mitsubishi Dion (the engine is 4G63). As the revs go beyond the 2000 rpm, the ‘check engine’ light comes on, then eventually the engine — if forced — cuts off. After a few minutes, the engine can start but it does not take long before it repeats. I was told by a mechanic to buy a new pressure pump. This was fitted but the problem has not gone away. Please help!”
Ummm… we think your mechanic needs to keep away from Runaround Sue.
