Testing coils on a coil over plug system?

[art leong]

I just tried to put it in gear with the wheels off the ground. And it goes in okay the wheels turning I can give it throttle slowly and it accepts it (won't crack the throttle on the jackstands though). But when I step on the brake the engine slows down and then dies when the wheels stop, unless I work the throttle hard.
Going to try to raise and lower the fuel pressure by 5 pounds and see what happens.
Another thing I checked was the injectors and the fuel rail and switched to different manifold setups.

It is definetly a lack of power thing. But it seems to be in the lower rpm range. Once it gets up to around 4000 it runs decent.
