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.
Do you
have the same problem?
Yes
No

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