OK
I cant believe it, i DID it. I managed to change the No1 injector.
the extension bar was the key, so thanks very much for this suggestion.
I did take some pics to catalogue the process, they arent brill, but may be useful, will post if ever required, but I am happy to take the intercooler off again, and catalogue the whole process as a guide.
I managed to get the lower half of the injector out after buying the correct 22mm bi-hex standard socket, plus 1/2" converter PLUS the 24" bar. Injector was welded in. One thing I noticed, the old injector sensor wire was facing "inwards", when I fitted the new one, it was facing "outwards". I am not concerned, because I was VERY careful when screweing it back in, did it by hand first to ensure I wasnt de threading, then nipped it up with my modified socket. I have run the car, at idle, for about 20 mins, no leaks. will get a run out this afternoon.
:thumbs
as for the difference, well, even at idle, its different...much different. seems more positive, when revving past 4k rpm its very clean, whereas before there was a bit of shudder. I havent done the codes yet, need to take it for a drive to get operating temp...
