Hey guys.. I’m in a bit of a concern here. I’d like to ask you guys on what to do with my 97 Ford F-250 powerstroke. So this truck has a good 360,000 miles on it, and was used a lot for work and all that, but on start up, about 10 seconds in, it’ll go into a baaaad idle, with the check engine light on. Now I put a new fuel filter Inline in it, and cleaned the return line, put new batteries in it, and that’s it. The idling returns to normal after being ran for a another good 10 seconds. If you guys have any idea what’s going on with my truck, that would mean a lot. Yes, there are some compression issues and that, and there is some blow by because of wear and tear, but it always ran so perfectly, even with that.
