Weird driveability

[Scorpius01]

Ran into a driveability problem that was intermittent. Would start and idle fine when in P and N, act like timing or a fueling issue when pushing the gas pedal for the first couple of time. Then it cleared up, sometimes feels down on power.
Then 3 weeks ago after running good it would not stay running unless I gave it gas. I did an S1 to S2 injector swap about 1.5 years ago……I took a pico scope to crank sensor, fuel pump with pressure gauge, throttle position sensor, MaF, coil packs all looked good, until I got to the injectors….4 looked great, 3 did not, 1 was def bad.
I luckily procured some used Nissan S2 injectors, cleaned and flowed these with a local company. Damn, problem fixed!
