Hey, I have a built KA-T with an AEM Infinity 5 ECU and a custom WireWorx harness. I'm have a strange timing issues. The car intermittently retards timing. Sometimes I will start the car and it will run and driver perfectly fine, using the timing light it is at 20BTDC where I set it. Other times when I start it it will idle rough with poor throttle response, the timing light shows the timing advanced to 0BTDC. I can start the car back to back in 1 sitting and it could do either of these things. What could cause this?
