I was wondering if anyone with a supercharger has had this problem.... Its been bout 2500k miles since i installed it, ran smooth and nice no lights. Check engine light came on 2days ago, so we hooked it up to my brothers diagnostics computer. The code read 305 or somthing like that dont really remember anyways it had to do with the knock sensor.... So we replaced that and disconnected the battery. took it around the block and came back on.... Has anyone had this problem if so please help me out thanks!!!!!

 

Ssmtl2nv has something similar

 

it's nothing, just make sure your coils are good and dont bang off of red line. it goes on b/c of the massive amount of air passing through the sensor, common on a/t and comptech said it's nothing. Plus I still passed inspection, no codes

 

yea took care of it lastnight... called comptech told me to rewire the acm, no lights came on and runs smooth again.. thanks!!!!
