I haven't tried a volt meter on it its kinda cold right now. It's kinda weird on highway speeds with the cruise on it doesn't happen. Looking at 65 to 80 mph . But driving to and from work city driving doing 35 to 40 when cruising just touching the gas to maintain speed it str arts to shutter like it's not getting enough fuel. I'll let off the gas and it will be OK or accelerate and no problem. Some times when coming to a stop a a red light stall, but just have to put in n and start and will run fine for a couple of miles of for the rest of the trip, another 10 miles.
