So 2nd time car went into limp mode, then refused to restart the ice. Cleaned the MAF sensor, car burns oils, so I check it daily. never let the car go below 3 bars of gas. 290xxx miles. This last time it did it to me, I put on a jump starter battery pack on the 12v battery and the car fired right back up. What is weird is I put a volt meter on the battery and it reads 12.6, I go into service check page (flipping the light switch on and off) it reads 11.6. any help would be great.
