What started as a slight hestitation on accellerating, which i thought to be E10 and long standstill due to Corona, became a very large hiccup and even threw a MILtantrum.
MES said misfire on cilinder 1, so took all coils and plugs out to examine. Nothing obviously wrong as far as I could see, so everything back in place except coil 1 and 4. Went for a drive and at first felt cured, but after a roundabout the hiccup and flashing MIL was back. As long as I accellerated carefully and kept it under 2000 rpm MIL went out and it was drivable.
Back on MES and presto: misfire on cilinder 4.
Exactly what I suspected.
Now with 4 new NGK plugs and 4 new NGK coils it's back to it's usual dr Jekyll and mr Hyde character. Me happy!
Back on MES to clear the codes and since it started to rain all tools and me back inside where we belong.
So if you have a slight hestitation it might be a coil on it's way out.
The new ones grip the plugs a great big tighter by the way.
