Today I changed the oil and fuel filter on my truck. Then as im on my way to a buddies house the truck started revving all by itself. Then check engine light came on. 10 codes. One being the P01693. One being ecm failure. Rest are high voltage codes, don't rremembe all of them off the top of my head. The truck will start and run then just sit there and rev by itself. Can clear codes then after a few minutes the process starts all over again with the same codes. Any suggestions? Even put the truck back to stock, nothing changed. Thanks in advanced.

This I'd have to agree with. But who knows. Check all of your connections/ grounds first. It could be something as simple as a connector you knocked off during the filter change

Make sure it's from the same kind of truck. Auto for auto or Manuel for Manuel. And you'll prob need a reflash after that. Hopefully it's a loose connection tho. Good luck

Tried the computer swap. Still no difference. Same codes and issues came back. Going to dealership tomorrow. Still got a warranty on it. Gonna see what they say.

I did find one ground loose. Tightened it up. Then the truck had develope a hiccup under load. Buddy suggested i check fuel filter seal. Did so, put back together then bam back to where i started.

Pull the Alternator and have it tested for AC sine and overcharging etc.

Well the ecm was the culprit. The dealership sure did charge a pretty penny since my warrenty again didn't cover anything again. On the plus side i am going to be getting some money back from the warranty people since i told the dealership that it was worthless.

Well i thought i was going to pick my truck up. I go to get back in it and now the abs and brake light on the dash is on, and the pedal goes straight to the floor. Was not like that when i dropped it off. Hopefully the dealership makes it right.

Better test that alternator too since it might be what killed the ECM. Might be killing the ABS too.
