code 52 knock sensor can't pass emissions
Would a knock sensor cause it to run rich? I've changed out the injectors, new tps, cold start injector and got it down about 70% from where it was. He did a printout at the test station and it shows running rich at high rpm in 1st and 5th. The rest of the gears it's flat at the bottom of the chart. The car runs awesome but I can't get by emissions. Any suggestions? Thanks!!!
