idling rough CEL codes P0300 and P1443
I'm new here, but I have a problem with my truck. It's a 97 ranger 3.0 V-6. I'm getting a CEL P0300 and P1443. Engine idles rough at start up and then settles down. On the highway it seems to run fine, but is consuming a lot of gas. When I come to a stop, it idles rough, then settles down. I think I have a vacuum leak somewhere. Doea anyone know where I can find a diagram of the vacuum line routes? Please help.
