freelander 1.8i fault

hi all
i am new to this!!
i have an 02 reg freelander 1.8i station wagon 35000 miles, she runs as if she is being held back, very flat. i have had her serviced by tune-up/ hometune and they reported to me that the emmissions were very high and that we had an error code on the diagnostics which read "0170 fuel adaptations out of range" from this he concluded that the lambda sensor on the exhaust manifold had packed up and needed replacing. this i did and no improvement has been seen
can anyone shed any light on the error code or what would be making my freelander drive so sluggish (i took a 51 reg 1.8i out the other day and it flew in comparison)
i have searched the web for the error code and have found nothing
oil and water are both fine with no loss of either or mixing!!
any help would be greatly appreciated
regards and heres hoping

Can't help you with your problem, but post it in the Freelander section and someone may help.

thanks mate i put it here and in the freelander section
just hoping i can get a reply that will help rather than take it to the rip off merchants that call themselves maindealers!!
thanks again

Not sure if you've taken it to be repaired yet, but if not I can give a few suggestions. Remember the engine is a Rover K series so there may be help in those forums.
Basic fuel injection relies on a sensor (oxygen / lambda) a computer and an injector.
Rich running can be caused by faulty lambda, usually very high HCs & CO.
Unfortunately, the MEMs system also factors in engine temp (&air inlet to lesser degree), which can cause rich burn too, again CO & HC high.
If the engine is too rich it will affect performance but check elsewhere........
I had a dislodged catalytic convertor matrix, it gave a lovely growl initially but then blocked the exit part of the housing so that it affected performance notably. Look (listen) for a rattle on acceleration, next time you're parked up, kneel outside the drivers side & try revving the pedal with your hand, also listen for rattle going over bumps. LR replacement expensive, so look for "ceramic" type, which IMHO is better designed.
Otherwise, if you can give me more info, I'm sure I can help.
I don't know any fault code meanings, by the way, so please don't ask.
Most ECUs are more robust than given credit. Failure is usually one of the peripheral components which suffer more abuse.
Last tip..............
Never overlook the basics: are spark plugs clean & correctly gapped, leads , distributor cap & rotor OK? Air filter clean / new?
If you're not mechanically minded, you'll need some help to do other bits, as things tend to get very rusty & stuck.
I recently tried a (non LR) specialist who were excellent & half the price of LR, so don't get too down. The freelander was britain's most popular 4X4 so not hard to find experienced help.
Good luck,
Paul

Good point, but some replies are worth waiting for .

I'm tempted to try & save face here, but can't think of anything plausible......

Any suggestions?

thanks for the replies guys!
no you are right i have not driven around for 14 months waiting for a reply!!
after waiting for a reply to my posting i decided i needed garage help! i took the freelander to country rovers in chard somerset and over the next six months they went through everything (and could not find out what the problem was. they eventually bought another freelander identical to mine so that they were able to swap bits from one to another to see if the could solve the problem! to cut a very long story short they swapped engines and all was ok my original engine is still on the workshop floor and noone knows what is wrong with it! 2days later the head went on the new engine this was then fixed and i was £3000 worse off overall! i have now sold the freelander and was happy to see the back of this bad experience.
cheers guys
