please help

[Del sol driver]

I have a 1993 del sol and i got some problems. When its cold it wont run at all i have to sit there and rev it up. Then when its at 1500 rpms it sounds like rev limiter. But when i pass it it seem fine
It only does it at 1500 to around 1800. Please help i have been messing with this for months now. Thanks
