Check the air intake and make sure no wash rags were stuck in there. It is slow in acceleration? could the car been damaged underneath? Squashed exhaust pipe or catalytic converter pinched? you need gas, electrical spark, and air to run the car. The computers try the best to make sure the correct mixture is applied to have the engine run at peak performance and have good emissions. If it is not getting enough air, or can't rid itself of air, that can cause power loss and set off a lot of signals. Have the computer read and see what the triangle with the exclamation is telling you.
