When I let my clutch out from a stop, I can hear a single knock coming from the engine compartment. Basically most of the time, when I apply torque to the wheels from a stop I get the knock, and sometimes into second gear. Anyone else have this problem? Also I have a K&N intake, and I got a cel last night, but I don't know if its from the intake or the 104 octane unleaded race fuel I put in. I disconeccted my battery today and the cel came on about 25 minutes after I reconected the battery. Anyone get a cel from UNLEADED race gas, or is it probably from the intake. Also the cel came on as I was parking from a run down the track.

 

Sounds like it could be something serious/dangerous. I would have the dealership look it over.

 

Are you serious? What should I tell the dealership I was doing when it happened (racing at the track) but won't they refuse service if I say that?

 

All you need to say is the following
Don't mention the race gas or race track, some dealerships are ******** about fixing, what they believe to be, an abused car. But I don't think it was from your driving.

 

yeah but what if they ask me what I was doing before it started doing it?

 

Say nothing, you are way too paranoid

 

ok, thanks. I bet it happened on my last run last night, I got wheel hop so bad my glove compartment flew open and all the stuff fell on the floor, it felt like I was off roading!

 

That's really bad. You might want to lower the RPM's you're launching at.

 

i launched at just above idle, it broke the tires loose after the clutch was all the way out! (track was shitty)
