      is there a return spring on the pedal or is the spring to return the pedal just the spring on the throttle body?

      my pedal doesn't return i have to go to the TB and push the cable back. and pull the pedal back up by hand or foot

      i'm figuring i need a new cable but before i order one wondering if there is something i can do.

      Are you sure your TB isn't sticking or that your cable isn't binding? Cause after I changed my cable I had problems with it sticking open. I lubed it all up with liquid wrench and that seemed to have solved it.

      i can rev the engine using just the TB and it works great i press the pedal and it stays like cruise control i can pull the pedal back but the cable stays in place the cable just seems to stick
      i have to go into the engine bay and pull the cable back.
      i'll try lubing it when i get home

      Check to make sure the grommet hasn't come off the firewall.

      Or that the plastic end that go into the firewall hasn't slide out of the grommet and is binding.

      Sounds like the cable is toast.
      You could pop the cable end off the throttle body and test it by hand to see if it's binding. If it isn't reasonably smooth spend the 20 odd $ and replace it.

      Indeed. The Autohauz one as it will also have the correct grommet for mounting on the valve cover correctly. The ones from Autozone,O'Reilly etc. usually do not in my experience they will feel coarse and stiff in no time. Then they get so bad in less than a year that you have to replace them for driveability sake. I have had an Autohauz one on for a couple of years now and it still feels pretty good.

      Hmm... I was talking to a guy with a motorcycle; he says good bike shops have a tool that clamps on to the cable end and injects lubricant by pushing down grease between the sleeve and the cable.

      Seems like a good idea; good preventative maintenance, get it slick to begin with.

      Anybody else hear of or know of anything like that?

      lots of PB blaster and me and someone else playing tug o war with the cable and its almost perfect seems like the PB has not yet reached the end still gets hung up before its pulled all the way back.

      but this is the least of my issues this whole alt vbelt is just getting to me.

      make sure the cable has not come 'unfrayed' @ the ends.

      loose windings will cause the cable operation to bind up fiercely.
      i good vibes... and sciroccos.

      And of course there is the most common thing to fail on these-the pedal bushing. Check that out before you do anything. A bad bushing can cause exactly what you are experiencing and is a cheap and easy fix.
