    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...

  4. 24in of vacuum at idle too high for the 2.8L?

    I did some research on how to adjust the 2150 carburetor on my 1984 Bronco II using a vacuum gauge. Every where I read, they said 18-20in of vacuum is normal for a healthy V6... I was able to pull 24-25in stable on the gauge while idling at a normal RPM.... is this ok?? I would like to add...

    Hey all, new here. Just got this 87 ford ranger 4x4 2.9 manual. It's not passing smog because the egr valve isn't getting a vacuum. Had a shop look at it and I've replaced: the egr valve, egr vacuum solenoid, egr pressure sensor, and on the recommended of the Latest shop, the ecu. About 200...

    Vacuum tubing?

    Where do you guys get your replacement vacuum tubing? My truck has the plastic lines that connect with rubber connectors and the only tubing I have been able to find locally is 3ft long which isn't enough and I really don't want to put a rubber splice in the middle. The guy at Autozone told me...

  11. Vacuum line severed?

    Yesterday I noticed that my vacuum line was snapped, part of it (about 3") was completely off... Would this be causing my truck to run loud? Also, where would I be able to buy some? It couldn't be more than a 1/8" diameter and is probably abit smaller. I've looked everywhere and nowhere has it.
  12. Heater Control Valve Vacuum Leak

    Hey guys, I have a 1997 ranger xlt with the 2.3. I found out today that I have a vacuum leak that is keeping my heater control valve from opening up, so no coolant gets to the heater core. I can't seem to find the right vacuum diagram to figure out where the vacuum hoses go either. I believe it...
  13. 4x4 hub question

    So the bearings are going on the front end of my 2000 ford ranger 4x4. I just order new hubs/w bearing but I am not sure if I got the right parts. This is what I ordered from rock auto http://www.rockauto.com/catalog/moreinfo.php?pk=4287453&cc=1362798 I guess I really wanted to know if those...
  14. HVAC vacuum lines

    New member. I have searched for the answer and found some help but not enough to completely help me with my issue. Had to swap out the heater control valve on my 1995 3.0 Ranger XLT. Replacement was easy enough. My problem is that the vacuum line to the heater control was brittle and broke...

I have a fuel injected, 2.3 liter With Manual Tranny and in any gear under load, at any RPM under 2000, it has no power, over 2k and it acts a little hesitant, but goes up somewhat normally, I suspect it is a vacuum advance problem, but this engine is fuel injected, and I can't see quite...

    Ported vacuum source?

    Can anyone recommend a good place to tap into a ported vacuum source? I would like to see if my accelerator pump bypass switch is still good, however all the Smog stuff has been removed and most, if not all of the colored vacuum lines have been cut and melted closed. Thanks in advance.:beer:
  20. 1988 Bronco II cruise control vacuum routing

    Hey everyone, First-time Ford owner here. I picked up an 88 Bronco II XLT to use as a winter beater back in November. The guy who owned it before me was a "mechanic"... meaning there are a lot of things done on it recently, which were all half-assed. New brake shoes on badly worn drums, new...
