While working on the fuel injectors, I somehow dropped a vacuum line(signal line I think) from the Boost Solonoid. I can not find a diagram anywhere that shows both lines coming off the solonoid, not even in the Pontiac shop manual. Car is idling terribly, but runs like a scalded dog otherwise, so I'm thinking it's the open vacuum line.
Also, how in the heck do you get to the back plugs?. I can just barely touch them. much less remove and replace them.
thanx in advance,

I'm not sure about the vacuum problem except to say retrace your work and look for easily broken plastic lines??
RE: the plugs! Some engines require tilting them in neutral with a special tool that holds it there.
There are many things on cars that are not DIY friendly and that's one of them.
Ever wonder why Ford and GM are going bankrupt? T
