A mate of mine has a 2002 astra 1.7 DTI with the Y17DT Isuzu engine. He came to mine today and asked me if i knew what was wrong with it as the engine is missing like mad when warm and also cutting out. I told him the common problem being the EDU and dry solder joints so he is swapping the EDU with another one from another car on monday to try. He's already swapped the MAF with a known good unit and that didn't work.
Do you think the problem is with the EDU or could there be other causes?
Can the EGR be cleaned on this engine? Is it hard? where is it?
Also there was a thread all about re-soldering the EDU dry joints but i cant seem to find it. Can anyone point me in the right direction.
