11 Fault Codes - Discovery II
Hello Guys
My discovery Series II 2000 with 180K on the clock even though still running great but after regural oil change and minor maintenance the mechanic wrote me down 11 fault codes as the services engine soon was on:
p1590 Manf Cntrl Veh Spd Idle Speed Control Aux Inpunts
p0420 Catalyst Efficiency Below Threshold (bank 1)
p1300 Manf Control Ignition sustem or misfire
p0308 Cylinder 8 Misfire detected
p1174 Manf Control fuel air matering
p0446 Evap Emission Control System vent Circuit Malfuntion
p1173 Manf Control Fuel Air Matering
p1171 Manf Control Fuel Air Matering
p0303 Cylinder 3 misfire detected
p0133 O2 sensor CKT slow response (bank 1 sensor)
p0306 Cylinder 6 misfire detected
As I'm out of the states, pretty sure that I need to buy a new parts, please somebody could advise me here
Thanks a lot

Well, you should definitely start by replacing your Mass Airflow Sensor, as that "can" be the cause of a good 9 of the 11 codes. Don't buy from the dealer - order from roverguy.com as he has them for about $130. good luck -
You have a smorgasbord of issues. But like the previous poster said. Start with a new MAF and clear the codes and see what comes back. 1590 is your 3 amigos, 0133 probably means you will need at least one new O2 sensor. Hopefully the misfires and cat code will go away after the MAF. You purge leak hopefully was at one point a loose gas cap. If you have not a tuneup lately new plugs and wires are a good idea also.
How long has the check engine light been on?
If for awhile, I would clear the codes, drive it for a couple of hours and then when the light comes back on you can deal with the current codes.
How long since it was tunes along with new plug wires and have the 02 sensors ever been changed?
