i am in need of an ECU wire/pin diagram for a 1984 bmw 325E because i need to check wires
this all started with a problem with my bmw it is blowing black smoke (over fueling) in the beggining it would run real ruff but then after 30 minutes it ran fine would idle perfectly not so much any more. many machanics said oxygen sensor or the computer but all is checked and ok i checked the coolant tempeture sensor which is puttin out 1980 olms at 30 degrees but i onlychecked the main one there seems to be a second one which im not sure what it is????? many other sensors have ben checked such as the referance sensore speed sensor idle air stabilizer valve, tempiture switch, throtle position sensor wich is leadin me 2 think thats its a broken wire thus is y i need the diagram for my ecu im going in circles here could realy use some help.
