Fuel Saving Tips
This issue has been reported with 100% occurrence on the Challenger/Charger/Ram forums.The stock intake manifolds are not properly torqued from the factory which leads to cold start, idle, acceleration and throttle issues.Everyone who has checked has reported that the bolts were loose and took multiple full rotations to tighten. Borrow or purchase an in-lb torque wrench and torque each bolt to 105 in-lb when the engine is cold. This has been reported to resolve cold start and idle issues as well as increase throttle response and even power output.
