I have a P0001 issue, and I noticed my battery had green acid corrosion on the negative terminal which I remove and clean. When I started the car the idle was way off. By watching your videos I got it fixed by turning the ignition on and of a couple of times. Did not know that I had to store the idling memory. Now that the car is back to normal idle I'm getting a P0016/01/02. Can you explain why it showed up? Thanks!
I'd go get battery and alt load tested and if good, clear the codes and see if they come back. Very possible you have bad battery, alt, fuel regulator and camsensor... but unlikely. Start with battery and alt test to insure ecm is getting good regulated voltage all the time, clear codes and go from there. And put dielectric grease on those battery terminals. And fyi, coke is the best cleaner for removing that acid corrosion. Then rinse with clean water after and apply grease.
