P0271 Cylinder 4 injector circuit high
On occasions with the engine hot after a brief shutdown (eg motorway service garage) when accelerating away I get a warning, the engine goes into limp mode for a few seconds before allowing me to accelerate away as normal. When I read the motor sensor failure I get the above code. Just to add to the confusion couple of days ago it was Cylinder 1 injector circuit high!! This problem started a couple of months ago and I actually went ahead and replaced all the ignition coils - car has done 120k miles so thought it wouldnt do any harm - however its still persisiting. Apart from this occasional glitch the engine runs extremely smoothly with no roughness or lack of acceleration. By the way its a 2005 2.0 JTS. Any help much appreciated.
