Dang it...whenever something gets fixed another thing goes wrong. What could be wrong with my car. We hooked it up to the my friends diagnostic tool and it gave a knock sensor error 304. What could be wrong? It seemed like everytime he cleared the codes and I would drive it, the CEL would not come on until i got anywhere near positive vacuum.

 

Do you mean p0304? What year and model?

 

I've got a 98 Prelude. I remember it was a knock sensor code. My friend told me the code was 304. What I can remember is that the CEL had 2 long flashes followed by 3 short ones. I know for a fact its detonating. Do you think it could be that I need to retard my timing? And how many degrees should I retard it?

Thanks

 

What's your timing set at?

 

I believe we set it to stock timing, however my car is boosted. I believe the stock timing is 15 degrees.

 

Ahh, boost. The forced induction guys should be able to help you out.
