New plugs , wires , cap , rotor , coil , tps , injectors , fuel pump , still doesn't run clean when warming up - has fish pull when cruising and seems to not have much power . 90% of the time it throws code 43 (knock system) about 5-10 seconds after you first start it but the engine light shuts off after about 3-5 mins of running. I also noticed the rpms climb ever so slightly when I press the brake or release the brake - some sort of a vacuum related problem ??? Tired of throwing parts at this thing. Has anyone had any experience dealing with the knock sensor system or anything that might help me.
