Huhu I had asked in a different thread before, but somehow I didn’t get any revealing answers. What makes a broken ZKD noticeable? So my car always bucks around as if it didn’t get gas, sounds so choking, always so 1 sec long or so, and then repeats when speeding up, is not always, mostly when it’s cold. The exhaust smokes pretty much as I think. It consumes quite a lot of oil in my opinion. oh, and cooling water I had to refill more often.. Oh yes and always when I turn on the car in the morning is that for 2-3 seconds at the rumtickern like wild, doesn’t sound so healthy… Do you know what? What else could that be? Any relay? Distribution cap or something?
