Question Need help figuring this out car won't stay on

Ok did a engine swap same non turbo motor off. A 93 supra .swapped all parts from old motor to new motor cause the ac and alternator and steering pump were different connectors to the harness but got the car running and now it won't stay on now you gotta keep feeding it gas just to stay on and also the car is running to rich and won't go over 4,000 rpm's it's like it's maxed out. Any ideas already checked the fuel pump and changed out fuel filter cleaned out gas tank , changed the spark plugs checked out the vacuum holeses . Oh ya and this car sat for ten years before we started working on it any ideas

Haven't checked the grounds and already did timing And no codes I took it to Toyota and they said it was gas tank but already cleaned that and dam thing is happing. It's to rich still what can cause that . I just got a new air flow mass and still to rich next I was gonna get new o2s but I'm running out of ideas

Agreed new o2s is the next troubleshooting step.

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.
