So the car started run odd less power and transmission not shifting into 4th. I have replaced both knock sensors and harness and a/f ratio sensors bank 1 and 2 sensors 1 and 2 plus 3 new plugs gap checked. Car runs and sound fine at least until the knock sensor code. It has some slight ticking from up top on right side but it's had it since I bought it at 160.000 and current it's at 175.000. Only other issue it has had was the front 3 coil packs went out with in a 3 month period about a year ago and no issue until now. What am I missing please someone give me some advice cause iv never dealt with kind of issue. Usually I replace the parts and issue solved. Part were Dismo or have ever you spell it but the parts are quality
