Engine idle help please
I have a 99 F350 with a V10. I just replaced all the spark plugs and a bad coil which solved the very bad misfire I had going on. I also just changed the fuel pump and fuel filter.
When I start the truck, it idles just fine, nice and smooth. After sitting there for a short bit, maybe a couple minutes, it starts to idle rough, not so rough that it's about to shut off, just a little rough. This lasts maybe a minute and then goes back to nice and smooth and stays that way.
I've thought maybe the EGR valve or Idle air control valve but I'm not sure if I'm way off or sort of close. Wanted to see if anyone on here knows what the issue is. Thanks for any help!
