for quite some time i've been having trouble with my knock sensor. it keeps throwing a code even after i have replaced the sensor,rebuilt the motor, and redid my wiring( thanks tweak). we just rechecked the timing and its set at 10degreesTDC. i cant possibly think of anything else that could be causing a problem. could a bad ecu cause this to happen? if it was bad wouldn't the car not run at all? i've tried searching but all people ever say is to replace the sensor.... i'm really needing some more ideas on what else i need to check. Thank you.

if a gauge wont tell me anything then how else could i watch the a/f ratio without taking it to a dyno? i understand that i need to spend big money to fix problems like these. But dynos get fairly costly (especially in Topeka, Kansas where there is virtually no real performance shops) and my car fund is running low.
