When I am driving at any point of pressing the gas, my car starts to jerk. This happens through all gears and is highly noticeable when gas is pressed all the way. Couple days ago I decided to wash my engine to see how easy/ clean it would get. Didnt see any problems until today when I went for a cruise. Could this be cause there is moisture in the vacuum lines, throw out bearing, clutch slipping. Also, I can hear a pop coming from the exhaust when at idle. Ill post a video tomorrow for more clarification!

It sounds like it might be spark related. Are you due for a tune up? Check those wires and the plugs...

You've gotten water inside the spark plug wells. Pull the plug covers and the coils off each plug. Use compressed air to blow out any water in and to dry the wells. Use same compressed air to blow out the boot end of each coil. Place a daub of dielectric grease inside the boot and re-install.

Don't wash your engine with running or pressurized water again. There are too many sensitive electronics whose connectors are water resistant versus water proof and too many ways for liquid water to get where it shouldn't.

checked them and found out that some water did get into the rear passenger side, number 7 I think. All is better now. I hope it doesn't cause anything to rust/corrode. Going to put some anti seize when the engine cools down.

Don't worry about corrosion. The engine heat will evaporate any remaining water. The liquid present was shorting spark energy on that cylinder causing a misfire. Now that you've dried out the worst of it any remaining will dissipate on its own.
