new problem! yayyy!....
Okay so I finally got my car running again, but under full throttle it goes fine until I let off at high RPMs and just dies... I have to sit and wait several minutes before starting it again or it wont start. The car runs completely fine at idle and regular driving, doesnt run hot, doesnt shake, nothing. I have no clue what it could be. Please help! Thankss!

Any codes? Sounds like the fuel cutoff isn't working and the engine is getting flooded with fuel when you let your foot off the gas. Never heard off this before but I would look into the aftermarket tune if you're tuned, a sticky injector, or maybe something's up with the throttle body or tps sensor. Just some ideas, bump so someone can help this guy out

I don't get it, haha. And yes it throws a code every once in a while, but the CEL will go on and off. It's off now, but who knows it might come back on in an hour. haha.

When I try to start it back up after it does this, it will shake reallyy bad and sound like crap for about 2 seconds then die again. After I wait about 5 minutes and start it back again, it runs like a champ. without flooring it of course.

Used AutoTap to diagnose it, the code it was throwin was Crankshaft position Sensor,, I don't believe that would be the reason this is happening.. Checked all the vacuum lines and theyre fine, any ideass???
