Hesitating while accelerating

I replaced the water pump, power steering pressure hose and pump, and fuel filter. I degreased the engine at a car wash and rinsed with the power hose. Now when I drive it chugs/hesitating from stop to accelerate. I took it to a shop who hooked it up to the machine MAF & map sensors working correctly but the computer is not controlling them. What can I do?

I bet you got water in where it should not be or knocked something loose. How long has it been since you washed the engine? Does this car have a rotor cap? If so remove it and dry it out.
