I've got another question. What does it mean when the temperature light flashes? It doesn't stay on so i'm guessing that it is throwing a code, since the light isn't staying on.

 

my wife has had her 07 wolvy in creeks and not a problem with sputtering. keep looking and your find the cause. we had i reverse light that kept flashing, but we turn the key off and turned it back on it hasnt done it since. There is one thing that i'm not happy with about this machine is there is no GAS GAUGE
