Had codes for high voltage on all sensors on engine. Also had code for even/pcm Proccesor. Replaced ecm. Those codes went away. Now i have codes for p0122 and p1295. Truck starts fine. When push throttle it idles up then back to idle. Installed new apps and still same problem. Checked voltage on pin 5 and have 4.97 volts. Is my new ecm bad?
