knock wont go away!!! please help
91 gst
car was knocking it had a bad knock sensor changed it, still knocked, got new 02 knock went away for two days, now knock is bad, it knocks randomly any rpm any speed any gear, sometime i can pull from like 30-100 not a single count over like 4 then other times it will just be like 30+ counts at like 17% throttle. im thinking maybe my fuel pump needs to be rewired, im running 9psi, walbro 190 and k&n air filter those are the only thing that isnt stock. please help
