So I have had my ZX for 2 months now and have driven it with this knocking sound a total of 4000 miles now. The noise is worst around 3k rpms. I can stall the car up to 2.5k no problem and there is no noise. The noise completely goes away when i unplug the back right coil connector. I haven't checked my oil for metal but I pulled the dipstick and didn't see any. When I gas it, the noise goes away. Has anyone had this problem? I don't think it would be a rod bearing because I drive the car super hard and it should have gone out by now. Any help?
