2007 Chevy Malibu jerks on takeoff
My Malibu runs and idles smoothly, during takeoff from say a stoplight, car jerks until about 15-20 mph and then is smooth, 178,000 miles, V-6 ,auto, runs fine sitting still or highway speeds, just jerking on initial starts, no codes, 3 shops have run scans on entire vehicle and nothing,please help, Jason R.
Well, if it only does it when it's cold then it's probably a fuel problem. Try cleaning the fuel injectors with some good cleaner first. As they age when they're cold injectors often don't work all that well. But I would also pressure test if fuel pump a week. Fuel pump will do the same thing when they're old and cold to take a while to build up pressure
