As soon as i step on the petrol it seems to be clogged. I have error messages that was showing misfire on #2, 4, and 7. the engine oil pressure sensor high voltage input is high that is greater than 4.5 volts. what should i do Link to comment Share on other sites More sharing options...
iroc Posted July 12, 2011 Report Share Posted July 12, 2011 Is it a p38 or a later model range rover? When was the last time spark plugs were changed? If there are misfire fault codes on specific cylinders then try swapping ignition coils / plug wires to see if the misfire shifts. Link to comment Share on other sites More sharing options...
