Land Rover Repair/1999 Land Rover Discovery 2


Sir i asked before about Land Rover Discovery 2 problems car is sluggish, Hill Descent light, TC light, and service engine soon (which flashes) light are all lit all the time. Today i had a diagnostic done on the car it came back with these codes: P1590 Idle control, P1300 Ignition system, P0308 Cylinder 8 miss, P0306 Cylinder 6 miss, and P0300 random miss. Also, the mechanic said that oil was leaking badly on the left side of the engine he could not tell where it was coming from. i would like some advice on what i can do to have it fixed any specifics you can give would be greatly appreciated.

Hi Tammy,

To speak to your various questions :

The cylinder 6 and 8 misfires are first addressed with new spark plugs, plug wires, and coil packs.  In my part of the US, that total package of work is probably $1,500.  You may wish to fit fresh plugs first as that is just a few hundred dollars.

There is not much I can say about an oil leak without seeing it.  I suggest finding a qualified service person to look it over

Best of luck
