No start + ghost codes, then code 11, then all clear??

Well after about 30 minutes of highway driving I got to my friends house, shut my car off and played some beerpong. About 3 hours later I go to leave and all I get is cranking and sputtering like it's juuust about to start but never fired up. After 4 or 5 failed starts I checked codes, I saw 3 codes (which i don't remember any exept a 31)

At a loss for what to do I reset the ecu for the hell of it and checked codes again, got "all clear" till I tried to crank it, then popped 11. Gave it 2 more cranks and it fired up like it was fine. Drove all the way home and sat for 3 more hours and fired up again like normal.

Anyone ever had something like this? I'm kinda lost as to what I should do... Still safe to drive?

What kind of air filter are you using?

There is no code 11. The rest of the codes would have been helpful, all we have for now is a possible AFM issue.

There certainly is a code 11. It's the most serious code the car can have and while it's present no other codes can be displayed.

However using that source I can see how you thought that. In the future use this one:

It's better but still doesn't tell the whole story...

Maybe beer pong had an effect on the code reading?

Lol no no, when those codes showed my friend was in the car. Diag wasn't jumpered right so I wiggled it while he watched the cel, when I looked in all I saw was 31, I then reset the ecu cause I wanted to make sure it wasn't a fluke. I drove the car a bit today and havnt seen a code, I'm going to check in diag again later tonight, but for now it's acting like nothing happened, running strong.

I can't remember the brand air filter but am a bit ashamed to say it was the top of the line....at autozone
how would that cause what happened tho?

I had code 11 but it went away. I still do have a mysterious starting problem too... but it doesn't sound exactly like yours.

Well car ran great the past few days and this morning, but we just had a rainstorm come throgh about 20 minutes ago and now I have code 11 again, motor still wants to turn over and even gets a revolution or two but the tach doesn't even jump. Seems like rain is causing a short somewhere because it rained both times right before I got the code....but I wash my car every week with no problem. Any ideas?

Still wondering about the air filter problem Mkiiichip mentioned

Does anyone know the part number for the main relay?
