Starts up fine, but after a couple mins of running the check engine light comes on and wont rev over 3k RPMs, occasionally dies. It is displaying code 14:

"a loss of IGF signal between the ignitor and the computer for 6 events"

I tried replacing the ignitor with one I got from a junkyard and and a new one I bought online, both prevent the car from turning over. When I put the old one back on it starts up first time everytime but the issue still remains.
