Check your wiring first and foremost. Then start looking into the ecu and throttle body afterwards. I have replaced an ecu on one and a throttle body on another car. Let me know if you need schematics. Do you have a scan tool you can see live data with? And can you clear the codes, then the car returns to normal for a short time?

I have Torque Pro on my phone I use it as my scan tool. Not sure if it can record live date. I’d like the schematics if you have them. I clear the codes and it runs the same. They come back right away. when I start the car cold. First time of the day it runs fine for about 1-2 minutes but then starts to misfire.

Not sure how well you will be able to see this picture as its from my phone. But your looking for 2-4 volts on both the yellow and brown control wires to the throttle body. Also obviously check your other wires for a short, or open aswell.Sent from my iPhone using Tapatalk
