OP remember SIC promotes Maxxsonics products with false statements close to a staggering 100% of the time. His use of Idiot and moron should not be used so loosely as he does as what is he? exactly stated. Now one run of 0g should be fine AND your car acting sluggish at starting after driving could be due to a failing alternator indeed. check the resting voltage of your battery with the car not on and with the car running and report back with your findings.
also try this :Turn the car on. While the car is running, remove the negative cable on the battery. If the car stalls and dies, your alternator could be bad
