Default Loss of gas power after buying gas

Bought gas for 2007 GS 350 and immediately had a loss of gas power. I was not able to travel over 40 miles per hour. A few times had to pull over going up a hills due to loss of gas power.
I ran codes at Auto Zone and received P0158, P0606, P0300, P0352,P0303.
I will try a new gas cap, assuming I did not get bad gas. I put fluid into the gas that helps if I received bad gas but it was no help. The Check engine light is on, VSC, traction control or anti skid and also the "!" is on as well.

Any ideas before I have to take to the dealer or an Auto Shop.

Thank you in advance and I am sorry if this has already been posted but I am new to this site.

Angry Same problem.....help!

FREAKIN DUDE AT THE GAS STATION COMPLETELY LEFT MY GAS CAP OFF AFTER PUMPING '87' INTO MY TANK ...NOW EVEN AFTER REPLACING CAP I HAVE THE SAME LIGHTS ON FOR A WEEK NOW. HOW DO I AVOID GOING TO THE DEALERSHIP AND PAYING AN ARM N A LEG TO JUST REMOVE THESE WARNING LIGHTS? WILL A BATTERY DISCONNECT WORK?

^ usually I don't recommend clearing the code. Best have dealer check it out.

if you still really want to clear the code, which will clear the check engine light too... you can borrow Autozone code reader and use it to clear the code.

What gasoline grade did you use? Make sure you used what you used because it is on your receipt slip (I keep all my receipts for end of the year taxes).

This doesn't look like anything gas-cap related IMO. You're having tons of misfire codes. Could be you picked up bad gas or your car has WATER in the gas. Might want to try the gas cap remedy first, then take it to a mechanic.

FYI: During my gas cap failure, I had no such problems. Car drove perfectly fine, it was just a CEL and TCS off.....I think that's about it. Wish you the best of luck OP!

No need for caps locks in your convos .

If it's obviously gas cap issue, go to autozone and just have them reset the codes. You're probably going there to pick up a new gas cap anyways, right?

Yup sounds like he put diesel in there, I would remove the fuel out of the tank.

Sounds like diesel to me too, 87 wouldn't cause all of the problems you are experiencing.

In most NY gas stations the diesel pump nozzle cannot fit into a gas tank receptacle...not sure if that is the same elsewhere.

I didn't know that, very interesting as that is not the case for FL. In FL all the nozzles are universal

Did you happen to fill up when there was a tanker there delivering gas to the station? I will never fill up gas when I see a tanker... when they deliver the fuel, it stirs up all of the detritus that usually just settles harmlessly at the bottom of the tanks underground - sand, scum, water.

Unless it's just a fluke then I think you got a tank with too much water.

I'm definitely feeling the same way Jay.... especially with the fact that the car still RUNS..... If it were diesel, the car would have died after about 30s-1min time on the road.
