Hi all, just bought 1999 freelander 3 door 1.8 petrol, that has failed emissions test on mot any one have any ideas on possible cause,
first fast idle test
CO reading 0.54 max reading limit 0.30 fail
HC reading 111 max 200 pass
Lambda reading 1.050 min 0.950 max1.090 pass
2nd fast idle test
CO reading 0.57 max reading limit 0.30 fail
HC reading 118 max reading 200 pass
lambda reading 1.040 min 0.950 max 1.090 pass
natural idle test
CO reading 0.49 max 0.50 pass
new lamda was fitted by previous owner before test, also new HT leads, vehichle wasnt retested and has been used on horse farm for last year, now i want to put it back on the road
drove it home 50 miles and seems to drive fine, previous owner said Head gasket and belt water pump etc done at 72k now done 101k no signs of water leak but did need to put about 1/2 pint water in when i got it home (like a fool as price was cheap and it was pouring down when i picked it up didnt check water level in header tank, possibly inlet gasket leak that may cause higher CO reading ???? but cant see any signs of leak
any opinions would be greatly recieved before i get bits done willy nilly
cheers all john9153
