1999 Flex fuel repeatable problem....
Hello,
When I first crank my 1999 3.0 flex fuel Ranger (160,000 miles) it runs great and will continue to do so until it warms up and I shut down the engine. After the re-fire it runs rough/skips until it cools back down. I get no codes. It will do this same sequence EVERY time. As long as I leave it running there is no issue...runs great. Plugs, wires, injectors and coil pack have been changed. Ideas?? Thanks!! Keith Last edited by spillmk1; 02-16-2019 at 06:01 AM.

Just a shot in the dark; but try removing the IAC valve and give it a good cleaning. Might help to smooth out the engine after you restart the truck.
