If you are looking for a SAFE place to administer the hydrogen to the engine, look to the valve cover. Yes, the valve cover. One valve cover has a fresh air breather tube connected to it. This breather tube connects between the throttle plate and the mass air flow sensor. You have the OLD 3.1 liter SFI engine. These engines develop quite a rattle with the plastic cam gear on the timing chain with any significant mileage, which for a GM product is less than 80K miles.
The other valve cover, or the timing cover has the PCV valve. this valve is closed at idle, and opens when the engine gathers speed (throttle opens...) which also serves as an anti conflagration valve for the fuel vapors trapped within the confines of the crank-case. Having a nice fire inside the crank-case is not a good thing. Put the hydrogen line between the Crank-case and the PCV Valve. This will not only open only when the engine is revved up, which is a "calculated vacuum leak" and the computer will self calibrate for this, and adjust the O2 and OBDII system accordingly. No messy worries over the computer, or the hot-wire mass air flow.
I have the dealership book on this engine, and since it is hard-copy, I would have to FAX the actual pages, or scan them and send via JPG to ya.
Keep going.
