Hello
Had to get towed in today...
So... I was driving WOT smooth as can be then it seamed like my motor slowed down ever so slightly... Like 2-3 mph difference...
Shortly after I began to hear a knocking/clacking sound and an alarm went off...
I shut it down and called for a tow to avoid further damage...
The knocking/clacking sound seams to follow the RPMS as far as frequency goes...
The noise occurs in all 3 gears
I ran it on the muffs and removed 1 spark plug at a time and the noise remained constant...
I can't tell where it's coming from because it's resignating through the entire motor.... With the hood on it sounds like the lower end... With the hood off its louder so then it sounds like the engine...
A little reasearch says it could be a piston rod... Pop shaft bearing... As well as others...
My warranty expired yesterday....
Any input or expert advise would be very much appreciated....

Thanks
