the final chapter...... well took it to an injection specialist and they have told me whats wrong... the ecu is trying to reduce the injector 'on' time to reduce the mixture, but the ecu is only allowed to reduce the injector 'on' time down to 2 milliseconds and wont go any lower thanks to the...

Well the freelander has had it's testbook check and no error codes or faults reported by the ecu.... The lambda sensor is running in closed loop and we are now stuck as to what could be wrong. Wiring loom has been checked and all signals are reaching and leaving the ecu, the injectors are being...

i tend to agree with you, after replacing all the obvious/common things its testbook time.... so have booked it in for next monday, and will keep you all up to date with whats going on. thanks for everyones help and advice so far (and saving money!) :)

ok will cancel order first thing in morning, not sure if they done an adaptive reset....(what is that exactly?) and yes the lambda reads .9v at 1000rpm/2000rpm/3000rpm, when you blip the throttle it can drop to .1 for a split second but then goes straight back to .9 and sometimes 1v.......

have just ordered the fuel pressure regulator on the injection rail, and the only thing on the entire system i have not changed yet! (another £52!) so will find out on monday when it arrives if that does anything, if not then i have ran out of things to change and its been a waste of £1400 (not...

just got the freelander back after replacing the ecu and having it re-programmed...guess what..... STILL THE SAME!!!!! have now disconnected the vacuum pipe for the purge valve and blanked off the inlet pipe where it fits, that didnt cure it either.... am now gettin a bit p*ssed off with this...

just spoke to a auto electrician and yes you do have to have it re-coded to the vehicle, the main control unit (ccu) talks to the engine ecu, and if the two codes dont match up then it wont start!. so its now booked in for tomorrow for reprogramming.... then i can get back to testing to see if...

sorry last post wasnt that clear.... will fire up for a second then die, can crank it over and over and will not start, turn ignition off then on then will fire up for a second then die etc etc.... like its immoblised?

well i have just replaced the engine ecu with an identical unit, and now it does not want to start? re-done the tps calibration, made sure all connectors are clean and no bent pins, dash lights up as it should, fires up for a sec and then dies and wont re-start untill ignition off then back on...

just for the latest update....have just replaced the inlet air temp sensor and no change, still over fueling.... :(

thanks for your reply, have done exactly as you suggested, ignition position 2 (dash lights on) depress throttle to floor and release 5 times. switch to position 0 wait a min then start. its still doing exactly the same :( i then tested the tps, 5 volts going in on top pin, ground on bottom pin...

i double checked the throttle cable and is returning to the stop position on the throttle body so its not that (worth a try though...) and the fuel is new as i filled it up from empty with 30ltrs few days ago. starting to wonder if its something to do with the tps (throttle position sensor) as...

Hi 50cc, thanks for your reply.... all 4 of them are quite sooty after only a few hours use, and all have the same shade of black so looks like the injectors etc are ok or would have expected one to be wet or a different colour...

ooops left out its had new platinum spark plugs and a new catalytic convertor too...

Hi, Plugs are expensive due to being platinum plugs but wouldnt substitute them for anything else as can give rough running/poor fuel economy on these, but they should last for about 30,000 miles so its not too bad... normally running rough when warm and rich mixture is the temperature sender...

Hi all, new to the forum so please be patient with me... :) really sorry for the long post but am trying to give you the history of whats been going on... recently purchased a 2000 on w reg 1.8 freelander with blown head gasket. Wanted one for ages and this one came up so thought i would bite...
