Why did you start adjusting the air/fuel mixture to start with? What was your problem/issue before messing with the adjustment? I ask this because you might be compensating for another problem.
To properly adjust the air/fuel mixture, you need a Volt Ohm Meter that reads 'Duty Cycle', like Sears model #82139. Your engine needs to be in the 'Diagnostic Mode' to get the duty cycle readings.
Try doing a search on the forum for "Measuring Duty Cycle", this has been discussed many times.

Well, the car has always ran rather rich since I purchased it in September and recently failed smog (obviously). So I tried leaning the mixture out. Oh, when the plugs were pulled they were badly carbon fouled, rich mixture indeed!
The car is now running, however, not as before. Also, I tired to take it for a run around the block, but its lacking all power. Idle seems fine, its just when I step on the accelerator in D or R that the car doesn't even acknowledge it. I have my pedal at WOT and nothing... The EHA was also tinkered with, could that have something to do with this problem?
One thing I have noticed since getting the car running (and right before making the adjustment that killed that car about 4 days ago),
is that the vacuum gauge is more to the left in all positions (P,D,N) now more than ever before.
EDIT: I just caught this mistake. It should have read,"is that the vacuum gauge is more to the RIGHT in all positions..."
