Hi, I recently purchased a Doblo 1.2 with 85,000 miles on the clock. After replacing a faulty coil, it runs great at speed but has a very rough idle. The code is PO300, multiple random misfire. However when I clear the code the car idles ok for about 20 miles of driving then the check engine light comes on again and the rough idle returns. Anybody got any ideas?
