Thanks for the replies. I did say I changed the injectors. I only changed the number 3 because like all people who know squat about cars like myself, I listened to a guy that said he checked them all and the number 3 was bad. Mind you I was not there when he made his diagnosis. So I didn't see him actually check anything. The one thing he did check twice was that the amount of the check I wrote him was correct. He was a friend of a friend.
OK, so I will start replacing hoses systematically.
In response to the other advice : I did change the three connectors under the coils. I also replaced the spark plugs with the Bosch Super Plus plugs gapped at .028.
I did notice a hose missing under and by the manifold. Hmmmmm. I will go check that now.
I will report in.
