Please Help Diagnose this Strange Problem
bit of a weird one here: My 147 1.6TS has just started doing this funny thing; at about 4500 rpm, plus or minus 250, it's a bit random, it often has a big stutter. Like an instant lift on power, and then it comes back again a fraction of a second later. When this happens the Tacho drops REALLY fast (faster than the engine- but doesn't quite hit 0 before it's all fine again).
After the stutter it's fine for a second, then flashes MCSF, which then goes out again straight away, and all is fine again until next time.
Initially I was thinking battery connection but I now realise that it's only the Tach that dies with the engine, and the Speed, Water Fuel as well as headlights and radio all continue to work fine. So now I'm thinking ECU or Coil pack problem....
Anyone seen this before or have any ideas?
