When I accelerate quickly from 70 to 80 and back off the throttle "quickly" the engine seems to almost misfire or stumble. Accelerate and decelerate at any other lower speed is no problem at all. In general the engine is smooth as silk. Any ideas on what is happening? Time for a tune up ... :) ??

Well I can stick my finger through a hole in one of the silicone hoses...

    MKII, 90-99 NA & Turbo
    My '91 Turbo has a coolant leak in one of the pipes that go from the front to the rear. Looking around, I see both are available (right seems harder to find) - 16577-74010 and 16559-74010, circa $150-200 each.

  6. Air vent to no where?

    MKII, 90-99 NA & Turbo
    What is the deal with the air vent aimed at the drivers crotch? I looked at the back and there is nothing connected to it? Is there supposed to be another piece that goes here? Pics below.
