kwerrett Posted July 26, 2008 Share Posted July 26, 2008 I have just replace the head gasket on a friends 1.8 Freelander, about the 6th one I have done on different 1.8 freelanders. As is usual being a friends vehicle it has now another problem. I used the modified gasket and shim, new timing belt also. It drives well, warms up OK, no overpressure in the system. However after about 40 miles or so it starts to act as if its running out of fuel, the engine loses all power and no matter how far down on the throttle your foot is the engine just wants to cough ad splutter. A bit like having the intercooler hose off on a turbo, no power but the engine will idle. Switch off and restart and it revs ok for a few seconds then does the same again. This only happens when its hot, cold start is good. Must add that after I did the headgasket the owner fitted a new exhaust system and cat, aftermarket cheap version. I mentioned this to him as it seems like that blocked exhuast type fault but he didn't want to believe that it could be a problem. I feel pretty bad about the way its running but I feel that the head and timing belt job are a seperate item from this fault. All vacuum hoses are good and in place, all electrical block connections are good also. Any help would be much appreciated. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted July 27, 2008 Share Posted July 27, 2008 A couple of wild guesses for you: Check the vacuum connection to the ECU Check the fuel pressure Quote Link to comment Share on other sites More sharing options...
viorelluta Posted August 1, 2008 Share Posted August 1, 2008 I'm not really a specialist in engines, but if the owner have replaced the catalysator, aren't the sensors a possible cause? Maybe you can check how the engine works without the exhaust in place (remove it). Keep us informed! Quote Link to comment Share on other sites More sharing options...
viorelluta Posted August 1, 2008 Share Posted August 1, 2008 Another possible cause is the sensor which measures the engine temperature. If it does not work properly, it tells the computer that the engine is still cold and it sends too much petrol. The engine may even stop. Check the indicator of engine temp.

FridgeFreezer Posted August 1, 2008 Share Posted August 1, 2008 The coolant sensor for the ECU is a good suggestion, the fact your temperature gauge is indicating the engine is warm means the gauge sensor works, I don't know if the FL has a separate ECU coolant sensor though or where it might be. Catalyst seems unlikely, the lambda sensor is before the cat so changing it would have no effect. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 3, 2008 Share Posted August 3, 2008 There are two temp sensors - one for the guage and one for the ECU. Les. Quote Link to comment Share on other sites More sharing options...
Exmoor Beast Posted August 12, 2008 Share Posted August 12, 2008 Our Freelander does something similar, again only after its been running for ages and only if its below half a tank of fuel. It comes on suddenly usually when travelling consistantly at motorway type speeds, if you can top the fuel up the problem goes away, if not its limp home at tickover or leave it for an hour and start off again as if nothing was wrong. Its bloody irritating when it happens but I try to keep the tank over half full and then its fine. No doubt sooner or later someone will know exactly whats causing it anyway now the 110s back I'm not driving the Freelander so its not my problem Will Quote Link to comment Share on other sites More sharing options...

Hamish Grundy Posted September 27, 2008 Share Posted September 27, 2008 Has anyone just tried changing the fuel cap? Maybe causing vacuum in tank? Ours does the same. If you leave it for a couple of minutes it starts again. Just leave the cap off to release the pressure. Have tried this on our other freelander and that fuel cap is fine, never has a build up of pressure when you take the cap off. Quote Link to comment Share on other sites More sharing options...

Sputnik 1 Posted October 14, 2008 Share Posted October 14, 2008 I had a power loss problem - was going round in circles trying to find it - finally stripped down fuel pump took out filter and back flushed it with clean fuel - the carp that came out was UNBELIEVABLE - did this till it ran clean - reassembled and hey presto no probs since ( touch wood ) - took about 30 mins start to finish - would be worth doing even if it isnt the sole cause of your grief good luck B) Quote Link to comment Share on other sites More sharing options...

THANKS FOR THE INFO IT HAS REALLY HELPED ME at this moment . Quote Link to comment Share on other sites More sharing options...
KarlNS Posted August 12, 2009 Share Posted August 12, 2009 Just had same problem for weeks losing power turned out it was exhaust back box that was blocked put new back box on not had the problem again. Quote Link to comment Share on other sites More sharing options...
vougese39 Posted August 18, 2009 Share Posted August 18, 2009 have you had the ecu fault read if you have a blocked cat the lambda will begin to read odd as the back pressure increases the reading will become irratic is the throttle switch working correctly Quote Link to comment Share on other sites More sharing options...
