If it's anything like the 4k's, check all the grounds, esp if there's
any running to the IM (intake manifold)

Hi Gang

I just got a 1989 Audi 90Q 10V.  It had been sitting a while, so I
the oil/filter and spark plugs and cleaned out the ISV, put a fresh
tank of
Super unleaded and a new battery.  Everything looks OK, & engine
compression is good on all 5.  The car will start and run but idles
very low
and when you rev it up it sounds like it is missing or not running on
all 5
cylinders.  And it is hard to get it to rev over 3500 RPM in neutral.
Needless to say it does not drive well at all, you have to slip the
just to get it up the driveway.

I checked all the fuses, especially the ones under the red cover that
"MOTOR-MOTEUR" which I believe powers the ECU

Any other ideas on what to check?

Thanks for any ideas!!
