Posts: 36 | Hey mate i've experienced the same thing, did it happen after you installed ur tach or before? is it really bad? most of my problem was due to rich mixtures at low loads, check your plugs if they are dry powdery black then this means your mixtures are too rich which could be caused by fualty sensors or a bad tune (wet oily black, your in a lot more trouble).. could also be a lean misfire.. faulty idle control valve or a number of other different things. ahhh the joys of efi. let us know how u go
