OK. My disco has 116k and I drive it about 45 miles a day.
I have a service engine soon light that came on about a month ago.
I had it read and it came back gear four ratio incorrect.
I canged out all o2 sensores and the maf sensor.
I still get the mis read.
Also, My AC condensor fan will not come on. I changed the fuse and it blu the fuse.
On top of all that I have a small oil leak I think.
Please help.

Was it only one code? By mileage you needed the O2's but most likely not the MAF unless you also have 2 lean codes, one for each bank.
As for the fan, sounds like the fan motor is locked up, can you rotate it?
Mike

 

No I have too codesone for the gearratio incorrect and 2 lean code also
As for the fan, I can not rotate it.
What should I do.
Dameon

 

OK, this now makes since. Are you running a K&N air filter?
The codes your are getting usually when the MAF dets contaminated and a K&N is the worst thing you can run in a Rover.
Get back to me.
Mike

 

Yes, I do have a K&N air filter.
Dameon

 

I would suggest you remove your K&N filter this morning and go back to a paper filter. I keep trying to tell people K&N filter will leave a residue in the MAF and then it is gone.
How much did you pay for your last MAF, I may have a better place for you to buy the next one.
As for the fan, get a new one on there real soon or you will over heat your engine and you don't even want to think about that expense.

Ipaid 127 for theMAF of atlantic british..
I will replace that filter today.
I can get a fan off of ebay used for 140 dollars
Or should I buy a new one.

That is your call on the fan, might also look on , http://www.roverlandparts.com/, they have pretty good prices and a 90 day guarantee.
As for the MAF, I know Rover puts a 1 year warranty on their parts but if you try and return it they will see the oil residue and denie the warrnty.

mike good news i hope. the new maf has been on for a few days an
code is gone for now at least. I purchased a new fan do you think I can replace it my self.
Thanks for the info on the parts store. Theirs a few more thing I would like to take care of.

Well, that is good news if the codes stay off, just keep that K&N away from your truck.
As for the fan, it is not real hard to replace, if you are at all mechanicily inclined you can do it.
