Engine Stall problems of the 2010 Dodge Avenger

Engine light came on. Got it diagnosed and code suggested changing the crank shaft sensor. Purchased part and had it installed by an independent mechanic. An hour later the engine light returned and the engine knocked while stopped at a red light and the car turned off. The car would not go above 35 mph. I was able to restart the car and drove it to a second mechanic. The codes suggested changing the sensor, and a misfire of the 1st and 4th spark plugs. The crank shaft sensor was changed, the throttle body cleaned, and all spark plugs changed. Still the same issue. The car will not go above 30 mph despite the gas pedal being pushed all the way down. Knocking engine and stalling. Took car to dealership. They suggested I allow them to take the engine apart for 800 dollars with no guarantee that this would fix the issue. Car currently over 80,000 miles approximately.
