Richard:

Good news and bad news. Good news is that you get to replace your ICV hose the easy way, with the fuel distributor removed. Bad news is that if the barb for the short hose comes out of the boot between air flow meter horn and throttle body, the boot is bad. Check the clamp on the throttle body -- if you can turn it, or the clamp is completely closed up (ends meet), it's shot and leaking.

Do yourself a favor and get new injector seals and injector holder seals (the plastic sleeve the injector goes in) and replace those at the same time, since you will be taking the fuel distributor off anyway -- have to remove the injector lines to do that.

The barb is out in the open with the FD off....

I did this in three rounds, it's MUCH better to do it all at once.
