Something blew up
2003 evo 8 24500 miles
Happened this morning off cold start I let the car warm for like 3 minuets then started to leave to go to class. 200 ft up the road 2nd gear 3krpms I hear a loud pop . I instantly shut the car off n pulled over, I look under the hood expecting too see carnage but no everything looked fine I start it again n it sounded like a v8 with huge cams ( vid coming once I go back to the car left it on the road to go to class) I can smell gasoline as if I were swimming in a pool of it also my fuel pressure gauage goes up n down, and when I go to drive its spitting smoke looks more blackish then white, but it's basically a chimmeny when on the throttle at all, and the car dosnt go over 5mph ... So basically I'm screwed I'm 3/4 months new to my evo so I know my basic knowledge but I'm no engine interal or tuning expert. I NEED HELP WITH THIS

If it won't go over 5mph it blew off a coupler and the maf isn't reading correct. Check all your IC pipes, they may look connected but pull on them and double check. It could of even blew a hole in one. I had the same thing happen and about **** my pants until I pulled on my upper IC pipe and it was off the TB. The 4G63's are very strong motors and it takes more then that to kill one!!!

do a test real quick- pull the plug to the MAF sensor on your intake. then drive around and see if it drives better. If it does, then you definitely have a popped hose somewhere. I know that sound! It sucks and its scary.
although, you could have some other damage hence the smoke... but just rule that out first by yanking that maf sensor plug, it puts the car in "limp" mode (didn't know about this when my hose popped off)

definitely a coupler man, check the licp connection to the j-pipe, cant tell you how many times its happened to me, some t-bolt clamps, hair spray, and cleaning the coupler and bead ends will do the job
