HELP! No Acceleration, horrible shaking and sudden smell of rotten eggs... bad gas???

Okay guys, I know there have been a lot of posts on this topic before but none of them have tackled this specific issue in the way that I am seeing it this morning. For starters, we have a 2010 Prius with about 135k miles. We just had the rear brakes serviced and an oil change completed last week. Here it goes...

A few days ago, I ran my gas tank further than I ever had. I read a post once when we first got our Prius that said not to ever do that as the system is sensitive to any gunk in the tank and when we run it low like that, gunk can get into the engine and cause issues.
- On Saturday I went to a cookout with a really low tank. My wife let me know just before I got into the car but I didn't have time to get gas so I figured I'd do it afterwards.
- When I left the cookout I noticed some sputtering when I accelerated, which, at the time, I thought was me running out of gas because it really only occurred when the engine was engaged.
- After getting gas the engine continued to sputter when engaged so I drove around for a bit, accelerated heavily in an attempt to force whatever was causing this to go through and out of the system. My thought at this point was that I ran my engine too low and gunk got into the engine...
- When my wife got into the car this morning, she drove away with two of our kids and immediately came back. telling me that the engine was rattling ferociously at start and take off, especially at an incline but at no point could she really get going at all.
- I got in the car and struggled to go around the block. When I stopped the car, there was a sudden smell of rotten eggs...
-There are no warning lights or anything either... which I find a bit odd.

WHAT IS HAPPENING!?

I've experienced the shaking on startup a few times. My solution was to simply restart my engine and it would go away. Never have I ever experienced anything like this before until I ran my gas tank too low on Saturday.

I don't even think I could get the car to the mechanic without a tow at this point... I appreciate any information, tips or tricks.

Thanks!

 

Thanks for the reply! That makes sense, but wouldn't that cause a check engine light to engage?

 

No dash lights at all. I appreciate the reply, that's sort of what I thought could be the issue but the catalytic converter comment from above through me for a bit of a loop because that should have caused a dash light to flash. Right?

Could this debri cause all the shaking and lack of acceleration?

When I took it for a spin around the block, literally every time the engine engaged it was barely drivable... in fact, to drive it at all I had to stop or disengage the engine so that I could use the battery power to just make it home.

 

I just went outside and let it run for a bit and the check engine light came on. Now I need to get a code reader.

 

Okay, so I got a code reader and checked the gas cap, my daughter "helped" me pump this tank so the gas cap issue was a definite possibility, but it was on nice and tight.

The code reader found five codes

P0304 - Cylinder 4 Misfire Detected (this code was found twice)
P0300 - Random/Multiple Cylinder Misfire Detected
P0303 - Cylinder 3 Misfire Detected
P07E8 - DTC Definitions not found! Please refer to vehicle service manual!

I haven't looked up what the P07E8 code is yet.... I figured I'd be able to do an internet search and it came up empty? I'm going to grab the service manual now and see if I can find it. Any thoughts?

 

Well this definitely supports my gunk theory... no? But the Factory Service Manual? Is this something i can get my hands on? I am a novice, obviously, but I appreciate your help. I wasn't able to find anywhere what that other code was either... which seems weird.

Also, as an FYI, I just started it and took it around the block... but trip down the street and back was actually perfect. Acceleration was fine but then when I decided to test a longer route, it all went to crap again and I couldn't get the Prius past 25-30mph.
