<E30> 88 325e - Fuel, Motronic etc... PROBLEMS

To all Beemerphiles,

My 88 325e is extremely sick.  The initial problem was when the car is first driven, after 2 to 3 blocks the 
car would die... no idle... I would need to give it massive throttle to keep it idling.  The next thing that 
happens (as I am giving it too much throttle) is black smoke would pour out of the exhaust pipe, as seen 
through my rear view mirror.

Modifications done to car:

	1) Hypertech chip (5 years ago)
	2) PFP Catalytic converter (6 months ago)
	3) Oxygen sensor (aftermarket) 6 months ago

What I have done to the car as of late:

	1) Replace both fuel pumps. (The new external pump buzzes more than the old one)

After no luck troubleshooting I took the car to a Local BMW specialist, this is what he found/repaired:

	1) Replaced the airflow meter
	2) Replaced the Sparkplugs
	3) Replaced the Timing belt and adjusted valves
	4) Checked and adjusted idle and CO
	5) Replaced Water pump
	6) Fan Clutch

Now the car doesnt die anymore but still has a constant random "miss" when idling.  In addition, the car has 
reduced power when accelerating in the high rpm range (4000-5000).  The mechanic also said that at high rpm the 
CO and HO levels were too high.  His next suggestion was to inspect the ECU and throttle switches...This trial 
and error thing is getting old.

This is where I need your HELP.  Please offer any suggestions and or recommend any Wizard mechanics where I can 
take my car to in the SF Bay Area.

Thanks in Advance
