Dear Scotty,

    I just replaced the knock sensor in my Celica and deleted the knock sensor code with my code reader, then after like 2 starts it brought it back up. Now I also have an irregular idle problem when i'm just sitting at idle in gear. It fluctuates anywhere from around 700+ - 1200 RPM's. Could this cause that knock sensor error to come back up? And, what can I do to stop this irregular idle, I've already cleaned the IAC Valve once. Please reply back whenever you can, it be much appreciated. And keep on the good car videos and still waiting for that car app to come out....
