It is not a wheel shudder but and engine shudder, it happens when I am coming to a complete stop, like at traffic lights. It's been happening for years and is getting worse with time and it's driving me crazy. It is not the engine or transmission as they have both been reconditioned and it was doing it before these were fixed. Could it be brake booster related? No problem with brakes, they work great. Anyone had a similar problem?
