If I'm getting the knock sensor code...is my knock sensor bad, like positively? Nothing else it could be? Also, 0111, what causes that? I believe its the Evap Control System code.

 

When you get an O2 sensor code and a KS code, it is uasually best to replace the O2 sensor first as this may clear the KS code. I don't believe this would be the case with the Evap control system. There are ways to test a KS before you replace it. Read the How-to sticky for a description of testing the KS.

 

My evap control system code showed up after I did my short throw shifter (had a shop drill out the bolts)...maybe its a leak or something of that nature? Not really sure what the evap system entails. Anyway, I will be replacing my exhaust later this week, so should I see if that clears up my evap control system code and in turn my KS code? My gas mileage is still right at about 20 mph, with me getting on it pretty heavily, and I haven't noticied any sluggishness with the car.
