[QUOTE="Frankensuby, post: 2584051, member: 569869"] What is bugging me is that you are saying that it bogs down when it hits. My only thought is that somehow you are drawing enough of a drop in voltage to start confusing your sensors, and therefore your sensors are adjusting AFR's and other various mixtures and timings to make up for a false reading. Usually sensors 'sense' the situations somewhere 100 times per second or more, depending on vehicle make, etc... But, usually the computer will automatically tap into the existing Accessories in order to avoid these complications. Hence the reason why when your alternator dies and your battery slowly drains running all of the cars systems (while driving) your head unit will shut off, and all of your accessories, which will buy you a few more minutes. The computer is key in this situation. I would REALLY go somewhere and have your alternator checked, and then if that clears, I would have your car hooked into a proffessional OBD-II reader (or whatever diagnostics are on your car. By the way, what CAR do you have?) and see if the car's ECU has been recording sensor malfunction, or low voltage warnings for key electrical components. When a sensor goes bad, these kind of 'freeze' frames are sometimes recorded, and the code will be ultimately recorded on the memory. [/QUOTE]
