spark plug question

hello to all

1500 miles since i change them today i decided to do a plug reading plugs are still white excep for very minute brownish tint
at the tip of the porcelin. when i check pin 3 at x11 somedays it reads 43 to 54% fluctuating then there are days like today it reads of scale on my fluke 88automotive meter and no matter
which way i turn the mixture screw it won't change but i
can make the car run rought or smooth as i play with the mixture screw. items that were change 6 months ago
idle control solenoid
fuel distributor+eha valve

ovp relay.
also at time when i turn the car on for the firts few seconds the car runs rought like if it was choking or running on 5 cylinders

Your profile say 92 190e 2.6. Is this the car you are talking about? How many miles on the engine?

Sounds like a leaking injector. New injectors have been known to be bad.
