I was doing a tune up and there is a blue connector just above the starter on the right side of the engine that goes into the engine block. Its on a 92 camaro RS 305..I put it back but it is cooked to hell

 

That is either the knock sensor wire or the primary fan wire.

 

The car has been running a bit hot...But the fan is coming on though...Where can I find a replacement?

 

I am not sure if you can get one at the parts store but my best guess is the salvage yard.

 

Thanks for the help..I did some broswing and it turns out it is the knock sensor just below spark plugs 4/6. I'll have to call around to try to find it. But in the mean time it didnt throw a check engine light. does that mean it is fine for now?

 

Should be fine.
