I let the car sit 2 days. Plugged in Protool this morning and monitored the fuel pressure during start up. Pump pressure was 120 psi before starting the engine (Pump primed). At engine start and idle, pressure increased to ~1100psi and held. Once I put the car in drive and started to give a little gas to pull out of the parking spot, I started getting the bouncing idle and car started lunging. Fuel pressure increased towards 2000psi and was not cutting out or dropping. After 15 seconds and the lunging stopped, the pump continued to act normal. So it appears the the pumps aren’t the problem.

Any ideas where else to look?
