troubled 1jz-gte

[Rahul]

hi guys ... i have a 1jz-gte 1992 toyota supra. lately after i start the car in the morning ... and drive it for 5 minutes, it misses very badly and dumps out a lot of fuel out of exhaust pipe and there is a rich fuel smell inside the car. i changed all the coils and the plugs and got my car scanned. nuthing came out. can it be caused by the excessive pressure in the tank as the cap might not be able to release the excess pressure or its the charcoal cannister. the only thing is it only happens when i drive my car 5 minutes in th emorning and after it does so if i park it for 15 mins and start again it runs fine all day no matter how much and many times i park it and restart it, next morning its the same thing ... pleas ehelp .. thanks
