the other nite i was comin home from the mall and a old integra(89) was all up on me and the we were racin' and bad news he smoked me and by like 2 cars. so my car was really slow and now the cel is on and i know it is probably the knock sensor because it always comes on for the knock sensor because i haven't replace it, so how much to fix at dealer or shop, cant do it myself its a cali spec and dont understand "how to" on it?

 

look in the stickies at the top of the page it tells you how to do it, and what tools you will need, its not hard. dont pay someone to do it because they charge you to take you manifold off, and that is not necessary. good luck
