Engine problems after wash

Hi,



I washed the engine on a 2000 Hyundai Elantra a day ago. I started the car today and got out on the road, hit the gas and got nothing, the car goes but slow sometimes and sometimes it picks up and goes normal. The engine like stalls. It like hesitates to go when I press the gas pedal but it picks up sometimes and sometimes it doesn't and it makes this noise that it didn't make before like interrupted engine noise. The check engine light came on also and it flashed for an entire minute when I drove the car and it's still on when I turn the car on and off. I opened the hood and the engine shakes and before it wasn't shaking at all.



Before I washed it I covered this motor a mechanic told me to cover in aluminum foil and covered most of the electrical connections even though he said I didn't have to and covered the air intake. After I washed the engine I gave the car an entire 24 hours to dry up. I also drove in stormy weather with the car before and it was pouring but the car worked fine so I don't know what's going on.







I need to go to work today hahahaha



I could go to this Aamco that offers free check ups but I don't think I can make it and I can damage the car more if the car isn't already ****ed up.




what should I do?



Please help.



Thanks!







I didn't find the right solution from the Internet.
