So i am sure this is the wrong section and maybe the wrong forum, but i used to know you guys very well and know there are alot of very talented people here with alot of toyota knowlege, and i have been trying for months to get this to run right and im out of ideas.
A little background: I bought a 1989 BMW 325i, within 2 short weeks i was bored as normal and wanted to try doing something new/different. So, true to my history, one day i was almost out of gas and thought oh hey lets swap the engine. i pulled the BMW 2.5l inline 6 and stuffed a 3.0L 7MGTE into it
Long story short, modified engine mounts, custom tranny mount, a large hammer, and some swearing and i had a toyota powered bmw. 
I tied everything in, finished all the wiring and driveshaft/Exhaust were welded up. Fired it up, YAY she run.....oh she doesnt. i have been over everything but for some reason i think i am clearly missing something.
1988 7mgte engine, rebuilt with mhg with w56 trans, running a fmic, lexus maf, stock ecu.
Heres the problem, The car is very hard to start, must play with the peddle alot and then once it does run it refuses to idle. The idle jumps up and down, less and less rpm until it dies.
Once running as long as i play with the peddle i can keep it running, and in gear driving down the road she is alot of fun, but the second i come to a stop the car dies unless i give it gas the whole time.
i may have missed some details, i appreciate any input in advance.
help me get this car running or i guess it will be sold off haha it is depressing looking at it beside the house and not driving it after all the work i have put in to it.
Thank you
Jordan
