    Thread: Curious throttle response

    1. 09-14-2012 01:19 PM #1
      My 95 OBDI Jetta has a funny throttle response during shifting. Under acceleration, when I take my foot off the gas pedal and push the clutch in it revs higher by a few hundred rpm. Also, if I take my foot of the gas and leave the clutch engaged, there's about a one second delay before I sense deceleration. I checked the butterfly on the throttle body and it moves quite freely.

      Any ideas what would cause this?

      Your throttle cable might be frayed, causing your cable to stay in a stuck position for a brief moment after you let off.

      Mine did that when the cable was going bad until it eventually stuck for a lot longer.

      I wish it was that. I'm moving the butterfly at the throttle body which would be moving the cable as well and it's quite responsive.

      I'm learning to get around it and actually leverage it. It's really only a below 3000 rpm issue. Above that, it largely stays at the RPM I lifted making for some really clean, hammer down shifting...ignoring the fact it's gutless....

      Still, having owned this car for three months, I'm really enjoying it mostly for the simplicity. I went online and can't find anything with a bunch of worthless bells and whistles. I wish I'd known what I do now in 95 as I'd bought several and rotated them until I died.

      Trying cleaning out your throttle body with some carb cleaner spray and a rag. Its best to take the whole thing out. Make sure you let it adjust again before starting your car. Keep the key turned to the "on" position until you hear the humming stop.

      He has a '95, it's an old-school cable throttle.

      Sounds like a lazy ICV maybe?

      The weird part about it is that if I leave the clutch engaged and back off ever so gently on the throttle, the RPMs actually INCREASE for a moment before they drop. It happens more when it's hot outside but I can feel the pedal move away and then come back when I'm bare footed.

      Check for a vac leak and EGR function.
