my rang rover is having loss of power and missfiring

[haimant]

my range rover has a sudden loss of power when accerlating it is very sluggish it doesnt matter if the engine is cold or warm. 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

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.

do Exactly as Iroc has told you then come back with your findings.
