I'm getting 1-7* of knock retard under normal acceleration, what are all of the possible causes of false knock? I don't have access to race gas, so I can't really test if it's real. I checked my exhaust and there's plenty of clearance everywhere between it and the under side of the car.

I also noticed while in park, if I gradually step on the gas very slowly, I don't get any knock retard, but when I blip the throttle real quick, it jumps up to 3* or so.

Anyway, bottom line, where should I begin to look? I have a scanner so I can watch all sorts of fun sensors on my car.

 

N E 1?

I would guess it is your headers, that is what typically causes false knock.

 

I've had my headers for 4 years now and the knock just started in the past year, I haven't changed anything either. Why would the headers just have started to cause false knock?

 

Bad gas, low octane.

 

Wrong pushrod length. I had quite a bit of knock also. Got the right length pushrods and no more knock at all. But if you haven't done any internal engine work, that's probably not it.

 

Nevermind about the headers then...

Maybe the knock module is just loose... tighten it down. Or it could be faulty.
