Default engine running lumpy

Hi all,
My mk4 Supra is collecting dust in the garage.
when I start her up she runs fine.then after a few minutes she starts to run lumpy.I'm I'm guessing here... its like it starts with auto choke and runs fine... then when the choke goes off it runs lumpy....
any thoughts on the problem it has???

cheers

Check for boost/vacuum leaks. You could also try cleaning the injectors and changing the fuel filters. Those are the basics...if you get that all done and it's still lumpy, please check back.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.

Check also the MAF sensor.
