05 Ranger Edge 3.0L - Rough Idle - Page 2 - Ford Ranger Forum

Hooligan and I both have the 4.0, so it's a bit different. I have a pretty good miss now because of a few things wrong.... When you drive, does it make a really loud whooshing noise? Or is it quiet?

3.0's are bad bout blowing the egr vac lines.. the lines are on the right side manifold and go up to a small gray box on the front of the air mainifold.. i would check that as well

listen for a vacum leak. see if you here a high pitched sucking sound, and if you do, spray carb cleaner on it (only when engine is cold, if its hot it could start fire) once you identify where the leak is coming from, replace that part, usually a cracked rubber tube. ive got a 4.0 it idled really rough and sometimes died, but went away once i got in higher rpms.
