So today I can to a full stop at the light and my G started to what fells like a jerk.
My idle stayed the same it didnt move.
Anyone every experienced this?
-Engine light was on since November 2013 P0430

 

Too much power. Unfortunate side effect of buying a G35.

 

LOL
funnie guy...no seriously all i have on is the 5/16 spacer, stillen ztube kit, af cats, stillen y pipe

 

P0430 is very very common for G35 drivers who change out there cats. You need to add a nonfouler to each.

But it wouldnt have anything to do with a jerking motion you described. The only possible thing I can think of that would cause a jerking motion when stopping is warped brake rotor or misalignment.
