Hi, I thought that may have been the case as i was finishing job in dark and unsure of two of the coils! Just reversed them, no good. After replacing plugs i drove to shops - around 1km. downhill and cold motor so i just cruised. No problems at all. then on way back throttled it expecting to hear that loverly turbo sound but only went to 10psi. Still ran ok though without boost. after a couple more runs it's getting worse. Boost very erratic. just had it going uphill on quarter throttle, 2or 3 psi and it's missing badly. took three plugs out and they are badly carboned up. this is after maybe 4km total running. could it be the AFM? I did have all the pipes off it overnight.
