I tested the 24# injectors with a '96 MP PCM and scanner. I am surprised that
your plugs tend to show a lean fuel mixture. At idle and part throttle,
both O2 sensors showed a very rich condition. After about 15-20 min.
of city driving, the first O2 sensor was outputting 'lean' and 'rich'
voltage showing that the computer had adjusted to the larger injectors.
The 2nd O2 sensor (monitors the cat op) showed a constant rich.
Going to WOT from any rpm, the engine bogged badly and carbon soot
came out of both pipes.
