BAD SHAKING PROBLEM

1994 Infiniti Q45

Engine problem
1994 Infiniti Q45 V8 Two Wheel Drive Automatic 160000 miles

Hi,

I am at my wits end trying to repair my Q45. Here is a break down of the symptoms.

1. It shakes badly when idling
2. Sometimes it won't start as if it is not getting fuel

What I have already done:

1. I replaced the mass air flow sensor - used part
2. I replaced the fuel pump - new - now it starts
3. I replaced all 8 fuel injectors - new - still shakes

Now it starts but it still shakes very bad.

Seems like it may be the vacuum hose the air flows thru between the filter and the engine.
