something isn't right. I'd like to think it has to be in that connector, since cylinders 6 and 8 are next to eachother. Those codes are for the injector drive circuitry, so if the PCM doesn't like what it's seeing and says it's the drive circuit, there's not much else it can be.
Our trucks will not pass most state inspections when carbswapped.

Motor ran good when pulled but it was from obd1 truck didn稚 check for codes before pulling
