just posting this to document it really
early mk2 round headlight 3f ecu made by bosch , part number ending J , see it has lots of surface mount parts , general better quality feel to it
later mk2f 3f K made by ken? less surface mount parts and these burnt /manually fitted parts seem the norm as we opened up another and its the same , the J one is mint
Abd 3f injection.
Start the car and runs fine for 3 or 4 min then idles low and cuts out, wont repond to throttle when chugging and ramind this way on restart unless left
my 3f conversion failed the mot today , 10% co
at 10% its running fairly normal , sounds and drives "okay"
so i gets home and mess with the afm , i can get it lower towards a pass , but it just hates it a pops and bangs and really doesnt like it all
all service parts new /good , o2 unplugged,temp sender looks good on scanner , tried another afm , messed with ign timing etc checked all i can think off , cant really get my head round why it wants to run so rich and wont /struggles near normal readings
earlier this year ive fitted full 3f mpi injection to my previously refreshed abd , still not running 100% and i decided to re seal the inlet mani incase it was leaking
i gets it off and find the number 1 end is oily . not dripping but a good wet coating of clean engine oil
thing is all breathers are vented elsewhere so i dont really get where on earth it could have come from ?
