Starts fine, it can idle, but when I accelerate it dies. Before it did this the engine would stutter and lose power, than it would die. Air filters good, fuel pumps work fine.

I would check fuel pressure but you didn't say if you gave it a tune up or fuel filter

use a volt meter to check voltage at the connector. at idle you should have less than 1 volt. at full throttle you should not have more than 5 volts. make sure that the voltage changes smoothly as the throttle opens. not sure which wire is which off hand. one of the wires will have constant power and one of the wires is a signal wire. you need to check the signal wire
