Helpful Websites About 2007 Chevrolet Silverado active fuel management, upon activation causes truck to jerk
2007Jul 30
(reported on)Silverado LT1 5.3L
- Automatic transmission
- 2,500 miles
When going steady speed active fuel management cuts motor down to 4 cylinders, upon slight touch of gas or small incline engine turns cylinders back on but when this happens the whole truck jerks like a misfire or a spark plug wire is off. This was reported to the dealer before the 300 mile mark. No resolution, GM reps states "unfortunately the engine is operating as designed, we are sorry for your inconvenience".

Engine jerks when cylinders activate when switching from 4cyl mode back to 8cyl. seems like misfire but carried to shop twice and they connected a computer and drove down the road and the jerk is felt when cylinders are coming back on. The do not have any sort of fix now but was surprised that the jerk was that bad and told me this was the worst one they had seen as of yet but that several people are complaining.
