    Omfg...I don't know anything about cars, and I can tell this question is a fucking shit show. On board diagnostics? Really? And what iac code? There's more than one...You've provided no info, and your worse than someone asking for a breast cancer diagnosis on a troll forum...

    My advice is to check your windshield wiper fluid and take your car to a real mechanic.

    Oh, and your car sucks....

    BAM

      Maybe if he checks the OBD he'll find the dreaded F-ORD code.
      Unfortunately it's terminal

        Fix or repair daily, or found on road dead...or aids? It's aids, isn't it?

          Fucked on race day.
          Found on rubbish dumps.

          Luckily it's not a Jeep so doesn't suffer from the hivplus but God, there's not much in it...

    Okay if u don't like what I've asked then why read it dipshit...why be assholes there is no need for it....and for the people trying to help ~thank you~ and yes most throttle bodies don't flood unless there's something wrong I thought when trimming is bad it wouldn't rev up right like it would have a hesitation right???

    Don't be a moron. Put in a new air filter. Buy a diagnostic scanner, plug it in for 5 minutes, and google up any of the OBD codes that the scanner detects while the engine is running. Put some injector cleaner in your gas tank while you're at it too.

    Here on IIN, all of us boys and girls would rather talk about sex anyway.

    Could be your timing chain?
    Maybe one of the plugs are dead?
    Also, check if your lights go dim if you press the hooter..could be that you are losing power somewhere because of exposed wire unloading somewhere.
    Check your air filter element as well.

      Lights do go dim amp gauge drops with rpms rises with acceleration

    Throttle bodies are on a fuel injected engine and do not flood. Only carburetors flood out. Sounds like it might be a timing or vacuum issue. Or a timing issue caused by a vacuum leak.

      a vac leak on them motors makes for a faster than normal/lean crackly idle

      couldbe a plugged cat too

        Yea but it also won't let the timing advance. I think the 94 still had a distributer.

        • donteatstuffoffthesidewalk

          yep 94 did have a sparky-spinner but they used an electronic advance not vac

          id still just throw an iac at it since its throwin a code and clean the maf since it takes 5 minutes and costs nothin

          and who the fuck comes on iin givin vague hints for tryn to troubleshoot a pickup truck anyway?

            A Ford mechanic. It seems that the mechanics at Ford have trouble working on my Fusion. They really have no concept of how a torque wrench works. So I could see them using this site to gain an insight on how to fix a problematic F150. :)
