I realised my 2005 jp wrangler check engine light is light i had just finished gassing the car bt forget but forgot to close the tank lid, could this cause this problem.

Is the yellow light a plain dot with no shapes or signs on it? If it is and it is on the fuel level gauge it is most likely a 'Low Fuel' warning light. Filling the fuel tank past a quarter tank should turn this light off.
For the steering check the steering fluid level. A low level makes the steering harder to turn as there is not enough fluid in the system to work properly. Top the fluid up to the correct 'Max' mark and bleed the system. To bleed the system is really easy. Start the engine and turn the steering all the way to the left then all the way to the right. Do this 3 or 4 times. Turn the engine off and re-check the steering fluid level.
The oil leak could be something more serious so I will need more information to help you. First check your oil level with the dipstick. It should be between the two marks on the stick. Too much oil in the engine can cause other problems.
Where EXACTLY is the oil spilling out? Is it from the filler hole and cap you pour the oil into when your topping it up? Is it the bigger, long cover on top of the engine that the oil filler cap is fitted into? Comment below an I'll see if I can help you more.

Does the check engine light come on, on the dash, when you turn on the ignition, before trying to crank? If it does not light up, then your ecu might be in need of repair.

excessive fuel pressure breach in the vapor canister assembly (most likely)... this is near the gas tank quick disconnect line near the tank is breached filler neck is breached

Sounds like you may have an issue with the check valve on your in tank fuel pump. When these go bad, you have to crank several time to build up enough pressure in the fuel rail for engine start. With a good check valve, the fuel pressure will not bleed off and the pressure is retained for the next engine start.

in order for the air to flow in the directions that we want it is in fact controlled by vacum from the engine look under the hood close to the fire wall you must have either a damaged vacum hose or it is unplugged look close to the fire wall.Also these vehicles will have a small tank called the vacum canister which will look like a black ball or on some of thse vehicles they look like a paint can they are all under the hood for easy access. Make suere that you are getting vacum from the engine and then it hooks up to the tiny hose leading into the dash board,.

Clean the inside of the MAF sensor with MAF sensor spray, it is made bt CRC.
