Hello, What I think of first with a power surge when stopping is something vacuum related. The engine vacuum is being used to operate the power brake booster. When there is a problem in the system, it can make the engine speed increase when using the vacuum. Have this area checked. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
