    Unplugged vacuum line- runs better - SOLVED: IAC

    I just replaced injectors and PCV valve. I pulled the top half of the intake manifold to do it. Old injectors truly need to be replaced. Now the truck needs some gas to start and almost dies when going down to idle. It catches itself and gets to a decent idle. So what makes it better? Pulling a...

  3. Rough Under Load - Fuel Smell - No Codes

    Truck starting jerking a little a few days ago at highway speed and then continued even at low speed. First thought was bad fuel pressure or blocked fuel filter. While driving/under load: Heavy vibration and sometimes jerks/bucks. Feels drive train related. At idle or rev up while in...

    94 F150 running rough

    Been awhile since I checked in here, but figured I should start here for problem solving.. Recently came into possession of a 94 F150 4x4 302/Auto. If the truck sets overnight it will tend to have a low/rough idle when it drops from high idle, and almost tries to stall. A quick flick of the...
  5. Rough idle on 02 v6 3.0 ranger

    As with many others, I have found myself facing the rough idle issue on my ranger. I just picked it up last weekend and since then I have noticed that while the truck is at a stop or sitting in park, the truck will idle normally and then every couple seconds it idles (shakes) more rough. RPMs...
  6. Rough Idle and Shake at Low RPM's

    I have an automatic 2001 Ford Ranger with 175,xxx miles. I know this has been asked plenty of times, but I feel that my case is a little different. The ever so popular rough idle with the 3.0 engine. It has been doing it for quite some time now. Also, my truck shakes when I hit 1500 RPM's. But...

  11. Anyone else have this problem? Help

    I have had this 93 4x4 supercab for about 4 months now and I freaking love it. The only thing that has been bothering me is a weird rough idle slash rev. When I first got it the idle was rough and about 1200 to 1600 rpm is would run like it was misfiring, but no codes. It would vibrate and...
