I am finally road testing my 2.0 restoration and haven't quite got it right yet. It starts fine, runs smooth idling or revved up in the driveway but on the road test it accelerated slow, with what sounds like valve chatter when I give more gas to accelerate. It wouldn't go over 3000 rpm in 1st, 2nd or third. I tweaked the timing a bit and it seemed to get better, less chatter and almost up to 4000 rpm. Suggestions, comments; am I on the right track?

also, in addition to the connection at the injector coming loose, which i have also seen once or twice, i would look close at the FI grounds. they are located at top of the case, hard to see with air cleaner in place but if you remove it you can see those spade connectors where they are bolted on , the female connectors on the harness get loose and may not even be connected, mine were working loose and would give me intermittent contact so i would get a burst of power and smooth running and then you could tell it was only firing at times on only one pair of injectors. but sounds likeit might me a easy quick fix for you!
