    BMW 3 Series Forum - Technical Talk on the BMW E21
    My 318is is horrible on idle and is drinking petrol like an m3. Put it on the old comp and it brought up loads of codes cleared em first took it for a 4 mile drive plugged it back in and the only one it 02 oxygen sensor. No big deal but which one is better a nkg or bosche one. Has anyone used...
