dodgyjeep Posted October 21, 2007 Share Posted October 21, 2007 Hello all Been having a few problems with my 110 2002 td5, upon accelerating hardish the engine seems to lurch and lose pwer temporaily, this seems to be random and sometimes happens more when it is cold. On looking at the ecu plug one of the things? is dark like oil, having heard about this causing a misfire do you think this is whet i have got and how much is it going to cost? Can i get away with replacing the injector loom or will the whole engine loom have to be replaced also how do i know if the oil has got into the ecu? had it at 80 on the way home tonight with no problem at all!!!! cheers...this sounds expensive..... mark Quote Link to comment Share on other sites More sharing options...

An injector loom is about £40 and takes an hour (at the most) to change. Is very easy to do yourself. However.... reading this line: upon accelerating hardish the engine seems to lurch and lose pwer temporaily, this seems to be random and sometimes happens more when it is cold One other thing is could be is boost pressure. The Td5 has a boost pressure cut point of about 1.2 bar at ambient temp, above this the ecu will cut the fueling until the pressure drops below that of the limit point. Which would cause the engine to lurch. The Td5 does suffer from seized turbo actuators (or partially seized), which will cause overboost problems... as can a previous owner shortening the actuator arm. The quickest way to find out if this is the cause is to get your 110 plugged into a diagnostic computer and look at the fault codes (over boost will be logged) and check the live data page on a road test. Anywhere near the midlands and I could do that for you Ian Quote Link to comment Share on other sites More sharing options...
dodgyjeep Posted October 21, 2007 Author Share Posted October 21, 2007 thanks ian, it is going into a good mate of mine tomorrow so i will ask him to plug it in and see if it is overboost, what should i clean the red plug with? Quote Link to comment Share on other sites More sharing options...

Electrical cleaner, or brake cleaner.... If the injector harness is leaking - and has been for a while - you will have to clean it a few times (after replacing the injector harness) before it will stay clean.
