HELP!!!!!!!.....1JZ wont idle!!!!!

[kuroi_tuki]

Hi! I have a 91 MK3 that i imported from japan which has 1JZ-GTTE. I loved the car, itz completely stock except the trust filter, trust exhaust, and cat bypass.......anway.... this came out of no where. I was driving normally. Next day, when i started the car, it didnt idle, i thought it was because i dont have full fuel, so i filled up the gas, and it still wont idle.........I can drive the car, but I have to step on the gas to keep the engine running, the funny thing is that once the boost goes to 0kg/mm, i can hear a leak the the turbo, but then i disconnect the battery to reset the ECU, then i reconnect the battery n start the car again, it was fine, but itz only the leak is gone, the idle problem still exist........o and one more thing, there r alot of black smoke comin out <--it makes the underground parking lot so foggggggggy........................any1 have any ideas???
