I just had a clutch installed in the GSR and after I got the car back, the speedometer is bouncing around like crazy when I accelerate, and is at 0 when I am just driving normal. I am taking it back to the shop to get that fixed, but for the past 2 days now, my engine has thrown a CEL after about 5 mins of driving. I have not checked the code yet, but was just wondering if the speedo being messed up might cause a light.

Thanks.

 

maybe the vss wasnt hooked up... check the code man
