What's your combo?
What meter are you using?
What size injectors do you have?
What computer ar you using?
What conversion harness are you using?
Have you set TPS?
Does the car run and rev with the meter disconnected?
Do you have the MAP sensor disconnected?

Was the conversion from a kit or junkyard parts? It almost sounds like it was from salvage yard stuff to me. Most likely it runs but when you go to drive it it dies on you right? Did you hook up the v.s.s. wires ?
-vehicle speed sensor wires, for the speed sensor on the tranny-

Alright, did you hook up the v.s.s. wires ? Plus, do you realize that the mass air computers have different pin locations vs. a speed density computer wiring harness?

yes! I jumped all the wires like the instructions told me the only thing i didn't do was the v.s.s. wires but the instructions also said that was optional. the instructions came from the tech section

Did you plug the map sensor vacuum line? Bap sensors require no vac. Although this would more than likely cause a surging idle instead of dying i would assume.

Ah!
Welp, you'd better do the v.s.s. wires, as that should fix your problem.
Let us know. :SNSign:
