Do you have a scan tool?
check the FICM voltage
if no scan tool try changing the FICM relay and logic fuse
under hood on driver side electrical distribution box, there is a grey colored relay probably front of box close to engine side.
if its brown or discolored replace it

My 95 did this exactly to a Tee. After trying several things, like cleaning/replacing MAF, fuel injection cleaner to no avail, I ended up unplugging my battery overnight to reset the ECU. The next morning, I put cleaned old MAF and put it back on. Then hooked up battery. Started up, no bogging at 2000 rpms, no stalling, etc. The new MAF was an aftermarket that I bought on Ebay for $86. My car didn't like the aftermarket MAF, so I wouldn't recommend. Anyway, that was 2 weeks ago, and everything is still running good. Hope this helps.

Your battery may not be holding its charge. Charge the battery and take a voltage reading. Then after a few hours take another reading andsee if the voltage has dropped. If that is alright, refit the battery to the car. turn off all the electrics anddo a voltage test. If the battery is discharging then ou will have to find what componant is drawing the voltage. I normally check the boot through the rear seats first.

As a former Audi technician, I can pretty much guarantee the coil packs are your problem.

Hey Mudkicker,
Who ever thought of putting an electric fuel pump inside a tank of gas........
Check your other gauges for accuracy. They do that when a ground is loose.
Check the wiring from the fuel tank along the longitudinal frame for frays and shorts. Plugs are secured.
Under the hood, passenger side, check the fuel pump relay. Switch it with one of the others to test it.
Bring the vehicle to an auto parts store. Ask them to break out he code reader. Check for diag codes
Comment me back
Mike.

Generally the computer is reading a problem with the fuel pressure being to high or to low. The ICP is one problem it could be and you changed it. The other could be Fuel pressure regulator control solenoid or problems with the injector (s).
